Fog Light Wiring in Rear Bumper

Hey guys.

I'm kicking around options for lights to put in a newly acquired Ace Rear Bumper (thanks Jason!). So far I'm considering an OEM style replacement set like these.

http://www.ebay.com/itm/05-07-MAGNUM...ht_2955wt_1216

With these weather pack connectors tapped into the reverse light circuit of my trailer hitch harness.

Would I need a relay for this set up, or just tap, solder, and shrink?

I've had mine tapped in with a relay for two years and no issues.

I built a separate harness and relay for mine, no problems at all with a separate harness...been almost three years now. Here's my project http://www.jeepforum.com/forum/f96/r...stall-1084677/

Did you have to run a separate power line to the battery for the relay or is there a constant "on" power supply in the reverse or trailer harness?

That looks really good! I'll have a factory bumper for sale soon if you want to branch out and make some $$ building one and selling it LOL

***EDIT***

Disregard that question, I found a site that explained the ways and wonders of relays and see what I need to do. Thank you both for your input.

I don't need the rear bumper, but I DO need an OEM spare tire carrier.....I've always had the stock rubi 32" BFG KM's on mine, but my spare carrier is cracking....

I can definitely help you out with that. I'm waiting for some fog lights to be delivered so I can start the swap. I will let you know as soon as the OEM carrier is off my gate.

Alrighty then, the factory carrier, bumper, and hitch have been pulled from my JK. Can anyone let me know if there is a loom I can follow to a contstant power supply for relays, maybe from the tail lights or trailer harness? I would prefer to get it inside without creating any more holes than necessary, or is my only option route it under the body and then up the fire wall to the battery?

I ran my wiring back to the battery, my only tap in was for the trailer lights, but that was a plug and play harness....

I ran 10 gauge back to the battery, did a ground at the rear and plunked my relay beside the battery....my theory is to keep all the relays under the hood and away from the road spray.

Tapping into any existing harness is not a good idea for a JK....

So you ran 10 gauge back to battery, installed relay there, grounded at the frame by bumper, correct? You used a plug to tap into your trailer harness, but wouldn't you also have to run that back to the relay and then again from the relay to your lights?

I installed a Mopar plug and play trailer harness behind the drivers side tail light, it had nothing to do with my rear lighting, it's just the only tap in that I've made.
My rear lighting is fired from the battery, I like being able to flip a switch and have lights, when ever, sometimes to flash the car behind me that's running high beams...know what I mean?
Yes, I grounded the lights at the rear, no point in running a good ground any further. I ran the positive through the frame in logical spots and stuffed the rest under the hood. I've got two other custom harnesses, one for my headlights and another real cool one that rallylights.com made for me...I built some custom aux. lights from Hella headlights and have high/low beam aux. lights....instant daylight when I flip both switches.... Of course I don't do that on the road..........
What is it that you are trying to do....exactly? Once you establish your wiring harness, lights are easy...heck, Hella 500's are cheap and you can swap out lenses to change the pattern...just depends on what lights you want.....

That makes sense now, my problem was that I was trying to figure all this out in my head and couldn't wrap my brain around it. Once I broke out the crayons and drew it up it seems pretty easy.

I'm putting lights in an Ace rear bumper that has cutout and brackets to fit stock JK fog lights. Since I'm no good at fabricating I bought a set of knock offs from eBay that way they bolt right in and I don't have to make a bracket or mod them. They came with a harness, relay, and switch so I'm leaning more toward using the switch now since I can gain some other uses.

Sounds good! I think you'll be glad that you added the switch, I use mine a lot...
