OK, this may seem like a stupid question to some, but I realized that the rear lights in my 88 aren't working properly. I need to repalce the sockets because they're badly corroded, but I'm trying to figure out what each bulb is supposed to do. I never was behind the Jeep before, so I don't know what comes on with brakes, what flashes for signal, etc. There are 4 bulbs in each light, and I don't know what each one is for. Figuring that out will help me trace the wiring to find where my issues are. Also, I have a 4-pin trailer plug. I believe it is factory because the tow hitch appears to be and there is a tranny cooler. I was under the impression that we had a 5-wire system with separate brake and turn signal bulbs, so that would mean there is an adapter to convert it to run with a 4-wire trailer system. Where would this be located? I think there may be a fault in that because 2 of the pins on my trailer plug are dead, and the other that corresponds to left turn/brake has a constant 7.5v with the signal on and no brakes, which does not make any sense to me.
