The headlight switch melted the new switch has different color wires

The headlight switch melted the new switch has different color wires 93 dodge dakota Wire colors are different and I cut the old one off before I discovered this. So now I don't know what goes where. I didn't leave any wire on the old one because I wanted as much wire as possible to work with. Could the new one that I got from the wrecking yard be the wrong one since the colors are different or does dodge use whatever wire they feel like on any one vehicle?
