Gotta 94 century special and the master switch went out inthe driver's door. Ordered a new one, but I cannot find a good enough wiring diagram to that tells me where each wire goes. My problem is that there are 3 sets of the same colored wire. (2-black, 2-brown, and 2-purple) I need to know how to check that I'm connecting the correct black wire from the module to the correct black wire in the door. Any suggestions?

 

Just look at wiring and label if needed while installing new switch. Or you can do 1 wire at a time. You may want to disconnect battery before starting this...at least have key 'off'/out (ie. not listening to the car radio while doing this)

 

I can recommend to come on a site on which there are many articles on this question. не сочтите за рекламу, друг пригласил в новую космическую онлайн игру NetAssault - это просто БОМБА, а не игра:
