Is up to the installer to test all wires with a DMM whenever possible.
Where exactly would the brake pedal switch be? I have to many wires to just cut the first white wire I see by the brakes. thanks
at the top of the pedal will be a switch and the white wire is the one you need . always test to be sure.
