light, fan relay install - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I want to install relays to run my headlights and, in the future, an electric fan. I have converted my truck to a 105 amp 12SI already.

Where have you tapped into the electrical system to run a hot wire to the relays?

Thanks

James

I believe I understood your question...if I have not ignore what I am about to say.

As was explained to me by XXL...I hope he does not mind me quoting him...

"As for a solid 12 volt source, there isn't one that big in the factory fuse panel. You'll want to run one from the battery. Make sure you use a good 12 gauge or bigger wire, fuse it AT THE BATTERY, and use grommets when going through sheetmetal. If you plan to have other accessories that require power, you may want to bring the battery lead in and create a "bus" with it. That way you can just tap that connection any time you need battery power. "

Hope this helps...

I was going to ask a similar question...but what want to do is something like this. I just want to know what relays I would need? Anyone know?

I got a couple four pin 30A relays from autozone. $5 a peice. Hook them up right after the dimmer switch on the way out to the headlights.
