Best brand? Ebay? Classic industries? Dont want a cheap budget kit.
There's a write-up here to build your own. --> http://nastyz28.com/threads/how-to-headlight-relays.100568/
I did mine a bit differently (4 relays) but I don't have the diagram handy right now.
I'll try to post that up later.
Here's the diagram I designed a four-relay system.
If a relay fails... You can disconnect the factory plug from the relay and plug it directly into the lamp.
The single power lead can be hidden in the factory loom running across the radiator support.
This is what it looked like when assembled.
The relays are "velcro"ed to the inside of the fenders near each headlight so the whole package is pretty much invisible.
I bought mine from Summit
I just use my stock wiring on both my 1979 Z-28 and 1981 El Camino SS with H-4 headlights
The relays make the lights brighter due to full power to the headlight itself. I tried that once with my 70 and did not like the outcome.
MAD electric has a kit, you might want to look at
That stock headlight switch has a voltage limiting ballast inside of it and it won’t like trying to block even more power when those H4s try to pull it. I would hate to see a dash panel catch fire as a result.
I bought an ebay harness. I hooked one up and kept the old wiring to the other light. I didn't see a difference.
You need to connect them both for it to properly work.
