I have a 67 that someone did a horrible job ( butchered ) all of the wiring harnesses. 1. Who makes a wiring harness for a novice to install and can I replace the dash harness without removing the dash?
2. The gas gage does not work...wires are cut somewhere / Can I just run new wires from the gage and a power source and the sending unit.
My funds are somewhat limited.
Suggestions ?

Go to Wiringharness.com they have really nice products Myself am a dealer for them and can get you a discount.

The new catalog has the new dash harness option to up grade the fuse box this is what I am installing in mine.

I'll second M & H Electric Fabricators!

I bought a foward lamp harness for my '66 Camino and it looks just like factory. I did change out the alternator with an external regulator to a 12SI 104 amp internally regulated alternator and they did the conversion for the wires as well.

You won't be sorry!
