well a few days ago i posted about having no reverse lights on the 88. well now it has only 1 brake light again.. this had happened a few months ago so i replaced all the bulbs. well now it has happened again.. i havent got the chance to really pull it apart and check anything but i got a circuit tester to check if im getting power to the connectors in the socket. if i am then i know its a bulb connection problem... but the only problem with that is the parking lights work.... but if not that means a short circuit somewhere or ground problem. cause all the fuses are fine. but first off what should i hook the aligator clip on the circuit tester too? aint it gonna be a ground? but any more tips?

All the circles with squiggly lines are bulbs.Blk is usually ground,and dots at the T's(where one wire meets another) are splices.

Wht=White
LT Blu=Light Blue

Those abbreviations indicate wire colors.Just follow the wires.


Keep in mind the wires could be completely different colors than what the diagram lists.One thing I can say is that the license plate lights use a brown and black wire,it's that way on my 80,and it's that way on a buddy's 95,I don't think they changed those colors.

yep looks like your looking for a Black and apink wire going to your rear back up lamps, and a black wire ground, So check the ground.

and ont he brake lights
Light green and a orange, going into the lamp and black gorund, with brown running out .
the righ tone is, light blue and orange.

Good luck, Have fun
