[72SB]

I am sure several have done this but I just installed the LMC harness on my 72. Did same thing in my 67 Camaro last year.

The harness relieves the full 12v load from headlights away from the headlight switch making not only any headlight bulb you use brighter but also all the other lights, including dash lights. The headlight switch now just triggers relays that connect +12VDC from battery + terminal buss on PS fender.

Install is plug & play. No cutting any stock wires. I just put a larger O ring crimp on one of the ground wires for the kit because the existing bolt location for another ground required a larger crimp eyelet. No big deal.

For those who have not done this, its a simple, good mod which improves light output. I installed Sylvania Silver Star Halogen headlights in the higher color temp version so the headlights look more like modern cars in terms of brightness and color temp but otherwise are same watt load as stock.
