To power to and after pedal switch and functions. I have parking, plate, and blinkers that are working. Does anyone have a good wiring diagram and or photos of others who have dealt with this issue? Thanks for you're help if you do
It's easy to pop those housings off. Check for voltage between the power and ground wires for the light itself (with a brick or something on the brake pedal) and then from the power wire to the body to see if the ground is bad.
It's pretty common to see a voltage drop, they used thin wiring, it's a long run and it's had most of two decades to degrade, 9 volts or better should be enough to run the lights. If you're not getting at least that, there's a problem.
I tested the pedal switch I'm getting power and single across it with good ground I think it's after towards the hatch or behind the rear rug I heard there's grounds back there
No haven't been able to get to it this week due to work. I'm going to replace the cabin fuse panel and brake pedal switch with new ones this weekend and go from there. If that doesn't work it's getting hard wired to signal side of switch for now to have something.
Since I suspect the brake light switch, I would test by first disconnecting its connector. Then I would connect a short wire between the PK/DB and the WT/TN wire terminals. If the brake lights turn on, then the problem is with the switch. If it seems mounted right, I'd remove the switch and replace it (I think they're too cheap to warrant repairing).
