Would anyone happen to know which color wires are left, right, stop, and parking in the tail light wiring harness? I figure its in the trunk. I tried a search and found nothing and I saw the guide on lexls.com but that is for the first gen. Just wondering if anyone knows of similar for the 1995 Ls400

 

I suppose we could figure it out but just use a test light like professional installers do. Do not power your trailer lights direclyly from the wiring in the trunk. Use an appropriate trailer wiring kit to power the trailer lights from the car battery or engine compartment fuse box and use the wires in the trunk only to trigger the running, brake and turn signal lights.

The power wire for the trailer lights on my 00 LS400 exit the trunk through an existing hole for an ABS wire and run forward underneath the car to the engine compartment fuse. A photo showing where the power wire for my trailer lights is attached to the engine compartment fuse box is in the following thread: https://www.clublexus.com/forums/ls4...n-hid-car.html
