Headlight wiring

I'm in the process of upgrading my headlights and I'm adding the relays. I have read alot of the posts on here about doing this but haven't seen anything about increasing the wire size to the headlight. So I'm guessing the original wire is sufficient. I do plan on putting fresh connectors to the bulbs.

Re: Headlight wiring

You can't hurt going to 12 AWG. But, I don't think the replacement connectors will be pre-wired for 12, more like 14 AWG and for the short run, it should be okay.

Besides, going to 12 AWG will require the next bigger size terminal, aka, 10-12 verses 14-16 GA.
Soldering the wires together with SN 63 resin solder and heat shrinking the connection will do the trick. Just make sure the finished solder connection looks like silver rather than gun metal gray to ensure a good solder joint.

Re: Headlight wiring

The advantage to the relays is it drastically shortens the path from the power source to the head lamps. The OEM design required power to flow through the firewall terminal block twice, through the switch (full headlamp current) and through the dimmer. There was way to much wire, and too many connections to adequatly supply power to the headlamps. The wire gauge should be fine.

Re: Headlight wiring

Well it has taken a while to have the time and it finally warmed up enough to work in the garage. I got my new Halogen headlights working today. I ended up buying a relay kit all made up, I tapped into the high & low beam wires from the switch. The relays came with 12 ga. for the high and 14 ga. for the low so I ended up running new wires from the relay feeds to the headlights and added new connectors. I soldered all the connections and heat shrink wrapped them. They are alot brighter, know they just need to be adjust. I have found some helpful info on that subject on TC.

Re: Headlight wiring

Cool! A foggy morning is an ideal target scenario for aimming headlights.
