Default Newbie needs help

I acquired my 1976 Corvette last July. It was seldom driven in the 20 previous years. Those who worked on the car before me made a mess of most everything. I removed the Camaro 305 and replaced it with a ZZ6. Rebuilt the turbo 400, installed Borgeson steering box, new front and rear suspension, complete new brake system, aluminum radiator and electric fans, electric headlight actuators, 17" tires and wheels, fuel tank. Every square inch underneath was cleaned and painted, powder coated or undercoated. All body mounts, bushings and bearings are new. Except for the trans rebuild and the exhaust, I have done all the work myself. The car runs and drives great. I am currently installing the Vintage Air and trying to clean up the wiring mess under the dash from previous owners.

Nice car. I was at the OU airport day before yesterday. Agree, you hardly seem like a newbie to me either.

Two current mysteries are: the yellow wire in the harness by the headlight switch that is attached to nothing, and the cylindrical object spliced into my brake light switch wiring. The yellow wire is at terminal M in the turn signal harmonica plug and I don't know where it is supposed to go. I have no missing wires in the headlight switch. I think I should remove the "resistor" looking thing from the brake light switch wiring.

The yellow wire from the harmonica connector should go to your left rear tail light. I’m guessing you don’t have a working left rear turn signal.

According to the AIM for ‘76, that’s a radio noise suppression capacitor. They put one in the brake circuit and another in the turn signal circuit.

Beautiful car and work. If you are thinking about switching to LED dash lights, now would be the time. Jerry

The left rear signal works as is, although it blinks slow twice then fast the rest of the time, like when a bulb is out. Both front and rear signals work L&R. Brake lights work. More info on the LED dash lights please! I have a few dash light sockets that need replaced or are missing. Have the replacement sockets, but changing to LED would be cool.

Do a search on the C-2 and C-3 forums, there is a wealth of information about the topic. Start with Superbrights.com. They have conversion charts that makes the switch easy. Jerry

I guess I should clarify the newbie thing. I am new to owning a Corvette, and new to posting in this forum. I had never worked on a Corvette to this depth before. I have been involved in rebuilding wrecks and restoring older cars, worked in a mechanic shop and a body shop when I was young. I have lots of tools and some skills. I relied heavily on this forum for tech advice during my build.
