Just get yourself a voltage tester, even the screw drivers with the light on the end work, flick between reverse park etc see when lights up. Or one prong to body work and other to cable to check you have the right one. Be sure to flick betweenthenright one. As for the life of me I cannot remember the colours I used. May e a bit vague but simplest answer. As everyone has a handy sets rough terminal with the light on the end no one ever uses right?
