molocka12 Posted December 5, 2004 Share Posted December 5, 2004 While helping a friend move into a new house I notice the plug to the lights for a trailer only have the tail lights working. The stop light & the turn singles both right & left do not work. It looks to me that the plug has the little metal pins missing to make a connection for the lights that are not working. Is there a quick fix or do I have to replace the plug it self? How do I go about doing so it appears the plug wires goes into the rear wheel well passenger side? Any help is greatly appreciated. Thanks Tony Quote Link to comment Share on other sites More sharing options...

Thanks Tony ← You could get an aftermarket plug and then use an ice pick type tester to determine which wires are hooked to what lights, then match that to the plug on your trailer.

dougjohn2 Posted December 6, 2004 Share Posted December 6, 2004 The trailer wiring harness does connect in the passenger side rear cargo area. To access it (assuming yours is like mine) you'll need to remove the panel in the cargo area on that side. To do this, you'll need to remove the aluminum strip closest to you in the cargo area, then GENTLY pull the panel loose from the body. The panel is held on with plastic clips. These clips sometimes break, but if you remove the panel gently, you shouldn't have a problem. The wiring harness comes up from the bottom through a rubber grommet. Trace the wire from outside, leading in to where it's cliped in. With mine, it was just a matter of unclipping from the wiring harness. Hopefully yours is as easy as mine was...

eleypon Posted December 8, 2004 Share Posted December 8, 2004 I tow my ski around a lot and i find trailer lights go out a very often. Before you dismantle you vehicle check the trailer light first. Take you vehicle to an rv shop and they would be able to do a simple test. Quote Link to comment Share on other sites More sharing options...

Is there an after market wire harness that will plug right in to the set up on the Lexus so all I would have to do is run the wire up into the truck wall & plug it right in Thanks Tony Quote Link to comment Share on other sites More sharing options...
dougjohn2 Posted December 10, 2004 Share Posted December 10, 2004 You should be able to find one just about anywhere that has trailering equipment - check your local hardware store or trailer rental shop. You could get the Toyota/Lexus harness, but they want more than $80 for the harness!!! You should be able to find one for under $20. Let me know if you need specific (detailed) instructions, I can check the factory service manual and provide the details if necessary.

molocka12 Posted December 10, 2004 Author Share Posted December 10, 2004 I had a Friend test the plug. The problem that needs to be replace is the Trailer taillight converter which is a black box that protects your truck lights from shorting out. I hope this converter box is a common & easy to find aftermarket item. Quote Link to comment Share on other sites More sharing options...
molocka12 Posted December 11, 2004 Author Share Posted December 11, 2004 I went to a Toyota dealer to purchase the Tail light converter for my 97 LX450 figuring it would be cheaper than a Lexus dealer but found out you cannot order just that part. You must order the whole package at a cost of several hundred dollars. The converter itself is a small black unit about 3" long x 1 1/2" wide that is taped on the back passenger cargo wall & has 1 - 6 pin plug to a 4 pin plug in it. So why than would you have to purchase the whole package when it would only take you about 3 minutes to change this unit with no tools involve?

dougjohn2 Posted December 12, 2004 Share Posted December 12, 2004 See if you can locate someone on the ih8mud.com list who's parting out an 80 series land cruiser. You should be able to pick up any part you want. Quote Link to comment Share on other sites More sharing options...

SKperformance Posted December 13, 2004 Share Posted December 13, 2004 this may help you iam not sure if it affects the american vehicles but it is for these years of Canadian ones not sure since you didn;t emntion the year. http://www.tc.gc.ca/roadsafety/recalls/rec...&year=&cmd=next Make: LEXUS Model: LX470 Affected Year(s): 1998 1999 Units Affected: 88 TC Recall #: 1999071 Manufacturer: Campaign Code: Recall Details On certain vehicles, water could enter the housing of the trailer towing wire harness converter due to inadequate waterproofing performance and improper installation location of the unit. A short circuit could occur which can cause failure of the converter, and, if a trailer is being towed at the time, can also cause failure of the trailer lights. In some cases the converter housing could melt or electrical feedback could blow the fuse, disabling the vehicle's rear lights. Driving without the vehicle tail and/or trailer lights will increase the possibility of a vehicle crash. Correction: A redesigned towing wire harness converter will be installed in a revised location. Quote Link to comment Share on other sites More sharing options...
