Headlight Wiring Upgrade

[Moriarty]

I’m going to give this a go (mostly because I want to do the flash-to-pass mod next), but could use some hand holding.

So.. I need to run two pairs of 12 AWG (one each from the left and right blue/red wires and one each from the left and right blue/white wires) which then wire into the accessory line of the relays. I was originally thinking there was one relay per light (one for left, one for right), but now I’m wondering with four wires and two connections if one relay is for the left and right blue/white pair, and the other relay for the left and right blue/red pair?

I have a white wire feeding each of the blue/white wires, and a red wire feeding each of the blue/red wires. Do I tape off both the red wire and white wire on the driver’s side, and then use the other two to trigger the two relays? Presumably matching red with blue/red and white with blue/white, if I had things right above?



Also, what’s the name of these connectors?



Thanks!

One relay for low beam, one relay for high beam.

Your connectors are called male and female Bullet connectors.

Yes, cut and tape off the original feeds to the driver's side lights, both high and low, and instead feed them from the relays that will also feed the passenger side lights. You do the same cutting on the passenger side, but those feeds will then act as the trigger wires for the relays.
