I'm installing a vehicle dynamics processor and need help with the following instructions

Read below

Of the two lead wires connected to the back lamp, connect the one in which the voltage changes when the gear shift is in REVERSE (R) position. If not connected, this unit does not work properly.

I need to know where I find this wire.

Thanks in advance

im guessing it is talking about 2 wires going to the taillights, use a voltmeter to test which one has a change in voltage when the car is put in reverse. simple.

Although I'm sure you could get a quick answer to this (including I could look it up for you), I'm going to tell you what I tell everyone else. If you are going to be working on your own Supra then buy the manuals. Call Jeff or Curt today and get them on order. They are ~$200 for the body, chassis, electrical, and engine manuals (2-3 books depending on the year of your Supra) and they are worth their weight in gold!! They will tell you how to find any wire in the Supra just for example.

Regards,

Dusty
