the brake switch connector looks different Fromm the harness that goes in. Looks like the switch is a pain to get out. So I want to just swap the wiring over. Can you tell me what color wire corresponds with the old wiring?

Wish I could help.. wiring not my area. Maybe somebody will chime in unless you got it figured out

Lol, 1994 is when the brake switches changed, if you'd have gotten a 93 you'd actually be golden.

This is for a 90 but the 89 should be the same:

Unfortunately I'm not at my computer right now so I don't have access to all my diagrams.
