Re: Under hood wiring

VetteVet has a good tutorial on the headlight relays and HEI. Can be found first up in the electrical forum. I followed his instructions and replaced the headlights with Sylvania halogen lights. Goal was better light with out blinding everyone else on the road. Brighter, whiter, and no high amp draw through the headlight switch. Saves burning up the headlight switch or worse. After all the mess with the PO's attempt at the HEI if I was going to do it all over I would stick with a late 70's early 80's GM HEI dist and cap with out all the computer crap. If you have a tach, take out the resister in the tach wire or replace the harness with a new on and wallah!, tach works.
Just my 2 cents...
