Flickering or pulstating Headlights

That will work, I used to do it that way when I had the old style voltage regulator. I switched to the new style regulator for better stability.

I hate to bug you again, on the relay installation, but my car's coil wiring comes from the Street Fire P/N 5520 ignition box direct, it has no ballast resistor and I ended up with 3 wires on the incoming and 2 on the outside. Thanks for your time!
