Look in a junk yard and find one like your and look at how its wired or go to a alt shop and ask them for a diagram.

Suburban towing package fuse box location


2005 Suburban Z71 4WD I had similar situation. No 12 volt positive to 7 trailer. Under my hood at the fuse panel, the red 12v + wire was connected to Stud # 1 which is on the left side of fuse box. There is a square fuse right next to this stud. I put a 40 amp fuse in it. I use this power to charge a battery in a trailer as I am hauling.

Sorry to hear about this Dale but I don't believe you have done anything incorrectly. Use your DVOM with key on to check for 12v at the pigtail wire.The main cable should always have 12v but the pigtail should have 12 volts with the key on and or running safer to check with just the key on.Check this out and we can proceed with further instructions.

With 4 prong and 3 extra, that will give you what you need for 7 prong for towing RV. If your not too experienced in that area, a mechanic at any trailer place, or hitch installation place or who knows RV wiring, should be able to do it for you in about 1/2 hr. or less. Testing the wires from your truck for what they do as in right , left, stop, running/taillights, etc is about the hardest part, and the 7 prong usually comes with what terminal does what.48e2ffb.jpg

Why isn't my trailer connector charging the RV battery? I placed a fuse in slot 106, but it still doesn't appear to be working at the factory installed pigtail.


Might want to bench test the trailer tow battery charge relay.

You can also jumper this with a wire in the relay socket, to test the wiring to the trailer tow adapter. This is relay R05

Installing a 7-pin trailer towing recptical on a 1991 Ford F150.


I believe you can look up the manufacturer of the trailer plug kit and find the wiring diagram there. On alot of the trailer plug kits, they have pics and diagrams in the package. The 7 pin plug (truck side) is available with the pig tail set up that plugs directly into the wiring harness for the lights. Then all you would have to worry about is the 2 wires for the electric brakes.

Wheelchair lift electrical connection installation on 1999 K1500 Suburban?


More than likely your looking at the towing package for wiring a hitch to your vehicle for towing a trailer. Probably can use some of that, but I'm sure if you stopped in at a GM dealer and explained what your trying to do, they'd have someone look & confirm for you that it's o.k. or not to use that harness, without a big service charge.
