Well, I guess "hope springs eternal". Toyota doesn't design and manufacture their vehicles that way. Wiring harnesses on Toyota vehicles are extremely specific to a partcular market and to the equipment specifications of specific vehicles. Not only will you not find wiring on U.S. Lexus vehicles for options available in other world markets, you will not find wiring for options available in the US market that were not installed at the factory on a particular US spec car. Just the difference between Canadian and US spec Lexus cars will make your head spin. US spec and UK spec Lexus vehicles are far further apart.

Steve, you are being extremely kind.

Laser cruise control was available on the RX400h in the US although it has been superseded by the radar cruise control option on the RX450h Just because your dealer didn't care to find an RX400h for you with it doesn't mean it wasn't available. Regarding the foldable outside mirrors, I doubt if the RHD ones from the UK will work on a left hand drive US spec RX without their ECU's, wiring harnesses and switch assemblies. Toyota doesn't make it easy to interchange parts among cars of various world markets like some European car manufacturers do. Toyota (Lexus) parts -- and particularly electrical components -- can be very specific to a particular market. Foldable mirrors are more of a novelty in the US where streets are wide and parking spaces are often huge and big enough to accomodate a Suburban/Subdivision SUV. It's not like in the UK where streets in small towns can be so narrow that cars sometimes click mirrors as they pass each other at a fairly high rate of speed. More to the point, with the not-all-that-reliable record of foldable mirrors on US spec Lexus cars that have them, why would anyone want to put older used mirrors on a relatively new RX400h? What are you going to do when they fail?

Since you did not provide the model year of your car in either your profile or in your question, I'll assume yours is a 1990 LS400 and give you a link to a four page diagram that shows the components of the front passenger seat on a 1990 LS400: http://www.toyodiy.com/parts/p_U_1990_LEXU...EPGKA_7101.html I suggest you change your profile to give the year of your LS400 so you don't have to remember to provide each time you ask a question.

Odd, the link works for me. I'll download and attach the diagram.

Assuming you mean auxilliary input there are several companies including VAIS that appear to offer products for your car: http://www.vaistech.com/products/home.php Googling "iPod integration" and "aux input" might find you more. VAIS seems to be the one most people use.

This question has been asked several times and particularly in reference to the LS. Some have talked about installing a louder flasher module but I don't remember anyone reporting back that they had actually done that. Remember the hood and fender top turn signals on some American cars? The 67-68 Ford Mustang had turn signals in louvers in the hood that were easily visible to the driver. A number of American sedans - Cadillacs, Buicks, Oldsmobiles - had tiny turn signals mounted in the tops of the front fenders just rear of the head lights that pointed back towards the driver. Maybe some top fender turn signals from a 1990 Cadillac DeVille would do the trick on your IS! Seriously, most people get used to Lexus turn signal flashers not making much if any noise. I did and I'm not exactly a "Spring chicken". If this quiet turn signal flashers is a big deal for you, I'll bet it wouldn't be a huge project to wire one or more tiny light modules (maybe LED) into the turn signal circuit and either hide them in the car's interior or outside under the edge of the hood closest to the windshield.

Here is a diagram showing the location of components: http://www.toyodiy.com/parts/p_U_1994_LEXU...EPGKA_8615.html Although the diagram sort of makes it look like the telephone ECU is in the car interior, it is really on the left side of the trunk behind the trim.

I wonder who this car with Eagle Eyes headlights belongs to? Cobra? Rattlesnake? I met my friend "Tobi-Wan" driving my old 90 LS as I was leaving a parking lot last Tuesday in my 00 LS -- hadn't seen the beautiful old thing (the 90 LS -- NOT Tobi-Wan!) in over a year. I might be driving it today if Eagle Eyes headlights had been available back in 2003 when I sold it. The ONLY reason I sold the 90 LS was that I having difficult seeing well enough to drive at night.

That's odd. Audio system mute issues from the dealer installed car phones have usually affected the sound from the radio, cassette player and CD player equally -- at least that is what has been reported in previous threads. Usually disconnecting all the phone system components will resolve the problem -- on some Lexus phone systems, two connectors have to be plugged together after disconnecting them from the phone ECU in the trunk. Yours is the first time I've heard of anyone having to unplug a connector from the head unit to resolve this type of problem. To illustrate my point, several of us on this forum have attached the mute wire on aftermarket phone kits to a mute pin on the factory prewire phone harness -- when a call is in progress on on our aftermarket phone systems, the audio system is muted regardless of whether the radio, cassette or CD is in use. In case you don't already have it, attached is the full audio system diagram for a 1994 LS400 Nakamichi system. 1994_LS400_Nakamichi_diagram.pdf

Cars sold in the UK, Europe and some other markets are required to have rear fog lights. The "funky cruise control thing" looks like part of the optional laser cruise control. The differences between cars sold in various world markets is endless and is driven by factors such as different regulations, income levels, tastes, and fuel costs.

18" wheels with 245/45R18 tires are automatically going to provide a substantially harsher ride than the 16" wheels with the 225/60R16 tires that were standard on the 01 LS430. Two reasons: 1) The lower tire section size leaves less to cushion the ride -- tires also act as shock absorbers. 2) The wider 245 tires will react to more road imperfections - more rubber on the road means that you are going to feel more of the road. I've assumed that subtle suspection revisions were made in 2003 when 17" wheels on 225/55R17 tires became standard on the LS430 and especially in 2004 when 18" wheels became optional but I don't know if that is the case. If your 01 LS has more than 70,000 miles or so on it, a front end clunk could be from worn suspension components. The first front suspension part to go on my 00 LS400 was the strut bar bushings -- don't know if the strut bar bushings on the LS430 are under the same unusually high stress as on the 98-00 LS400 though. The Euro-tuned Sport Suspension option wasn't just a different set of shock absorbers. The option included different springs, suspension bushings, front and rear stabilizer bars and a variety of other components. A list of the components is at http://www.toyodiy.com/parts/g_U_2001_LEXU...L-AEAGKA_2.html

Thanks, Jim...yes, I had seen this schematic before, but the resolution is so poor it did not help. Hmmm ... the resolution of the drawing looks pretty good on my display. Have you removed part "58804A PANEL SUB-ASSY, CONSOLE, UPPER" and then removed the screws so you could remove "58833A COVER, CONSOLE, UPPER". If you don't see screws holding part 58804A in place, then it may be held in place by friction tabs. I sometimes use a stiff putty knife wrapped with electrical tape to prevent scratching when removing interior parts held in place by friction. I also have some plastic trim removal tools that are specifically made for this purpose. My assumption is that bolts holding the rear of the console down will be exposed once these parts are removed. I've never removed the center consoles in an RX but I have removed the center consoles in a 1990 and 2000 LS400 and a few other cars. The consoles of both the LS400's were held down at the rear by two bolts ... maybe the same on your RX - something has to be holding the rear of the console to the floor. On the two LS400s, I had to pry out the console box and remove some HVAC ducting to expose the two bolts holding down the rear end of the console.

Maybe this drawing will help: http://www.toyodiy.com/parts/p_U_1999_LEXU...WPGKA_5806.html

Toyota sells numerous versions of its cars in various world markets -- no different than other car manufacturers. The standard level of equipment for its Lexus cars sold outside North America has generally been higher -- sometimes far higher. The fog light "pilot" you noticed in the instrument cluster is likely the indicator light for the rear fog lights - not for the front fog lights.

Have you taken your GX to a Lexus dealer to have the problem diagnosed, done the appropriate groveling and been refused? I'm not sure I've seen a pattern on when Lexus will fix a TSIB problem on an out of warranty car but they seem more flexible if the warranty has expired fairly recently. If you can't get Lexus to fully fund the repair, you could try to get them to split the cost.

Sorry, I didn't notice that you are in the UK. LPS features vary among world markets. For example, some people in the US want to roll up their windows with the remote buttons on the key -- that LPS feature is not available in the US but it is in some other countries.

There have been a number of past threads on this forum in which people have expressed strong opinions on both sides of the argument -- aftermarket and OEM. I had an aftermarket windshield installed on my first LS400 after driving it about 10 - 11 years and then drove it another couple of years with the aftermarket one -- I couldn't tell the difference except of course the new aftermarket windshield was flawless and the original OEM was badly pitted. My wife's Camry windshield was replaced several years ago with an aftermarket one and we can't tell any difference in quality. One issue you may run into is that all the OEM colors may not available in an aftermarket windshield. For example, my 2000 LS400 has a bronze OEM windshield and, last time I checked, bronze was not available in the aftermarket. Not that it matters since I prefer gray anyway. IMO, the main issue is less with the windshield and more with the experience level and skill of the installer. On my 90 LS400, I tried to address this issue by having my windshield replaced at a body shop owned by the same company that owned a Lexus dealership. The body shop subcontracted the work out but at least they checked the quality. Also, the body shop didn't particularly recommend using Lexus glass -- they said they had had good experience with aftermarket glass so that is what I went with.

Good one, Python! What was that jcrome04 said recently about chrome rims? "I personally wouldn't buy chrome wheels for my LS. Cheeeeeeeeeee-Z!!!!" hmmmm

Changing LPS (Lexus Personalized Settings) requires a rather expensive handheld tester and the appropriate program card. Some non-dealer repair shops have the equipment if you want to avoid the dealer but the dealer is more likely to have a program card that allows all the customizable settings to be modified: http://www.lexus.com/pdf/service/SC430_LPS.pdf Review the list at the link above -- you might want other settings changed. A setting I found useful to have changed is to keep the interior lights on the maximum amount of time. Some people might like the headlight auto off time increased if they frequently park in dark areas.

There are a number of companies that repair Lexus radios -- often at prices far less than what Lexus dealers charge for an exchange radio. Google "Lexus radio repair". I shipped my radio head unit to a radio repair shop in Florida ( http://www.carstereohelp.com/ ) for repair -- got excellent service from "Bob" who apparently runs the place.

Doubtful. They appear to be quite different: 1994: http://www.lexls.com/images/models/pages/UCF10ii-06.html 1997: http://www.lexls.com/images/models/pages/UCF20iii-06.html

An in-dash navigation unit sure looks nice. I spent about 30 minutes yesterday installing a Garmin 260W GPS on a bracket in my wife's 11 year old Camry -- the power cord is mostly hidden behind the center console and the Garmin turns on and off automatically with the ignition switch. Total cost including the 260W from Costco, a Panavise "Garmin to AMPS" conversion bracket from eBay and a AMPS extension bracket from Pro.Fit was about $190. It ain't in-dash but it sure is slick ... and inexpensive.

There may be some confusion in this thread about terminology. The part shown in the first post in this thread is the removable navigation hard drive -- which Lexus calls a "harddisk" in the replacement instructions -- see the attachment. The removable navigation "harddisk" looks very similar to a hard drive in a laptop PC. Yes, the removable navigation "harddisk" is sealed and contains an actual nonremovable little spinning silver disk like all hard drives do -- amazing what one can find out with a hammer and chisel. If the dealer could not update the navigation in your 99 GS400, it probably meant that you have the most current harddisk navigation update and that there is nothing newer: http://www.sewellpartsonline.com/parts_det...88792&all=Y The maps in the last 98-00 nav update are already five years old which is an eternity when it comes to navigation maps. Lexus could surprise us but I don't think anybody thinks there is going to be another update for the old 98-00 nav system. commercialbrokerage, maybe it would be easier to look for an entire replacement 98-00 navigation ECU on ebay -- it would likely come with a removable "harddisk". Look for a nav ECU or harddisk from either a 98-00 GS300/400 or LS400. Or, like I said previously, try to contact one of the guys on ClubLexus who has replaced the OEM navigation in his 98-00 with an aftermarket navigation system. Maybe he would give you the "harddisk" or the entire nav ECU if he hasn't thrown the entire nav ECU in the trash -- it's not exactly worth anything/much.
