OR

you can run switch wires through the boot inside that marker lamp and down into the cab. You can use the rear defroster or rear wiper fuse for your switch power. Hope that helps.

You can always pm me your info. and we can go through the process over the phone too. ..might be easier.

I was posting when you were posting... thanks.. I'll PM you!

I'd like to run just the wires from the lights to the engine bay, and do everything else from there.

Hi you can get small 12 volt relays up to 100 amps. The ones we use at work are about size of 2 standard relays and are 80 amps.

Or you could use a starter selenoid.

hi he was to use a big starter sol, it has to be a continuous duty one.

I talked with PIAA today and they suggested 2 30 amp relays each protected with a 25 amp fuse using 10 gauge wire on everything up to the lights.

One thing I don't understand is that the PIAA relays are 7-10 amps, but are protected by a 20 amp fuse. Do the PIAA relays have something extra going on??

Anyways... I think I got everything I needed today.

I'm going to run 4 lights x 4 lights. I'll route the 10 gauge, one + one - down each A-pillar then wire everything up from under the hood with direct connections to the battery.

Tim... you have PM.
