1968 Camaro Z28 wiring issues, please help

Please help! I have a 1968 RS Z-28 with deluxe interior and tach/gauges. When you apply the brake, the dash lights, console gauge lights and front parking lights go on. The turn signals, 4 ways, headlights and brake lights all work fine.

One other electrical issue I am having, the parking brake warning light does not come on when the parking brake is depressed. The wiring is all hooked up and the bulb is good.

This car is a survivor; with all original unmolested wiring.

Any help would also be appreciated,

Thank you,

Re: 1968 Camaro Z28 wiring issues, please help

1967 and 1968's have a very weak ground of the instrument cluster. It is basically a paperclip at the top screw and never did the job. Most folks install a rear ground wire to the dash frame.

On the brake issue, there are two connections for the brake light. One is a switch on the parking brake side of it and the other is a switch on the side of the brake line distribution block under the master cylinder. But again a ground issue may be to blame.

Here is an old thread picture of one that has the added ground wire. Other end is attached to the dash support frame with a screw. I have also seen the ground attached to the top where the Speed Minder buzzer would have mounted. Either location will work well.

As Brian already stated, I would check all of your ground connections.

I have the ground for the high beams at the top of the cluster in tact; I also have a ground wire on the bottom of the cluster. Any other ideas? Thank you for you ideas and comments!

Is the ground at the console good?

Re: 1968 Camaro Z28 wiring issues, please help

I went through my grounds behind the dash and throughout the car. I am not sure what I did, but the problem is fixed. That being said, I sill can not get my emergency dash idiot light to work.the bulb is new, and the emergency brake wire is hooked up and the mecinism seems to be working. I also have the proportioning lock valve hooked up. Again any help would greatly be appreciated.

Re: 1968 Camaro Z28 wiring issues, please help

You will have to test the emergency brake (aka parking brake) switch with your multi-meter for continuity. But if you bypass the switches you should get the light if all the wiring is working, either switch can cause the line to be grounded. Does the light flash on at vehicle start?
