Traile backup lights

I'm trying to add backup lights to my trailer. I know it's the center pin on a 7 pin connector. The problem is that the black with green tracer (trailer
Backup wire) plug is laying near the fuse box under the hood. I can't find where it is supposed to plug in.

I also want to hook up the interior lights of te trailer to the auxilary pin. Which also has no power. I think they both are located on the same plug under the hood that is just laying there.

Ran across a couple threads about this. There are 2-4 pin plugs just laying on the fender with no place to get plugged into on my truck. Anyone got a part number for these missing relays that are suppose to be on the side of my fuse box or even a pic. Thanks again for any help

ok you are missing the relay box thats what they plug into. it is part of the trailer tow package which you are missing. the relay box has 2 relays one for the trailer charge and the other for backup lights the box is supposed to be mounted to the back side of the fuse box

Ronnie beat me with pics, but the part# of both relays are FOAB 14B192-AA
The part# of the small harness going to the two plugs is F6TB 14A346 P260Y AA
I'm assuming that harness and relay base are one piece so that # should get you both. Probably get the relays separate.

Perfect!!! Thanks man!!! Heading to the junk yard in the morning.
Another quick question, neither of those relays work w/out the truck running correct?
Got the week off work so I went up the hill to my buddies and snagged my trailer so I could do a few things. Backup lights/side lights - replace existing lights w/ LEDS, maybe add some other 120v lights inside to run off of my inverter in my truck. It already has a male plug on the outside and a outlet on the inside. So I'll just tap into that.

Thanks again for the help.

My owners manual says the same thing but the two plugs laying behind the fuse box on the fender tell me something is missing. After taking another look there are 3 plugs laying in behind the fuse box. IDK. 2 plugs have 4 prongs and the other is different.

I think one of those is for the auto trans harness, not used on ZFs.

The one I'm holding had a red and white wire. The one that is mounter on the fender has what I see a couple yellows in it and some others and the other has an orange and one with a black with/green tracer and some others. I can verify the other colors in the morning.
So I would guess the one with the yellow wires in it is my supply power to the relay and the one with the orange and black/green ( matches the colors of the rear of the truck side of the trailer plug) is the load side goin to the trailer. Correct?
