I spent about 2 hours tonight crawling under my Lexus and reading through these forums regarding an aftermarket hitch install on the GX470.
I have a new 2006 GX470, with KDSS, Navigation, and Mark Levinson. I am wanting to put a Class III type hitch on it.
It looks like there are a couple of aftermarket hitches that may work on the 2006.
Curt Mfg 13445 (I think U-Haul carries the same hitch with a different model)
Draw-Tite 75155
Here is my confusion.......
Under the Lexus, I can see the 3 predrilled frame bolts on each side. Two are close together and look larger like a 12mm bolt. On the driver side a tow hook is attached, which I assume I have to remove.
There is a another hole on the frame on each side about a foot farther back. Looks to be smaller like an 8mm bolte.
So do I just remove the tow hook, and torque down the 4 bolts that come with these 2 hitches?
It looks like only 3 predrilled holes on each side. However, some of the trailer hitch install instructions show 4 holes on each side. Could there be a difference for 2006?
Next issue regarding wiring. I do NOT need brake control, just lights. Most of the aftermarket sites say you have to hardwire. (some suggest a Modulite) However while under the Lexus, I found a couple of wiring connectors back around where the tow hitch would be connected. One was 3 connectors in a gray rubber sleeve. The other was a 5 or 6 connector in a round black type connector. Both were female I believe, and nothing was connected to them. I guess I can get out a voltage meter and check each connector while pressing the brake, turn signals, etc. However, does anyone know if these 2 connectors are prewired? If so, do I just need some kind of adapter? Again, I just have a simple (4 wire) trailer connector.
Sorry for the long post. But after reading through everything here, there seems to be a lot of confusion on the tow hitch on the GX470. I have installed several aftermarket hitches on my other Toyota vehicles. All were pretty simple. However, I don't want to order the wrong parts.
Thanks to all in advance.....
