Is200 towbar wiring HELP

[Gurmin]

hi just fitted a towbar to my Lexus but I'm stuck on the wiring I need to know what colour are the wires for each light on the car so I can connect to the relay cheers

This company has a list of makes and models for towbar wiring but nothing comes up when I click on the Lexus IS200, may be worth giving them a call to see if they will provide the PDF for a small charge.

Either this or trace each wire for rear lights,brake lights and indicators to the bulb sockets to get the colour codes.

Back at my old workplace we used to have something like this; you basically  plug in the wires from the harness and towbar wiring and then it lights up when connected correctly and operated.

 

There are a few guides? out there like this but no idea if it will apply for your case, I've never fitted one before :D
