Replaced the brake light switch on my '87, plastic bushings for the pushrod went bad and had to come up with a workaround, got it all back together and the lights work properly, but now I have a drain on my battery that takes it down to nothing, not sure if it's due to the new switch, or if the wires are reversed, I can't find a good source of which way the wires are supposed to plug into the switch, I have a pinkish-red wire and a light blue with a black stripe, going into a brown plastic connector that can plug in both ways. When I got the truck, it had the 4-pin switch which I've learned is meant for cruise control, mine doesn't have it so I replaced it with a 2 pin one.
