Under bumper Hitch options

[fourfourto]

I just ordered the curtis hitch,I bought it from JC whitney it came with a free 2" drop receiver.
I also ordered a 2 " ball ,hitch pin lock, curtis hitch skid plate and a wire plug kit.
It all came to $183.93 total including shipping using a $50 off coupon I recieved in a email the other day.

Hitch and wire plug installed ( I mounted the plug upside down behind the bumper I thought it might get damaged hanging near the hitch)

I will pick up the electric trailer brake this week.
The trailering brake looks like easy install theres a Dk blue, Lt blue,+ and - wire under dash.

The problem is were are the wires I need for the back?.
I thought the rear cluster had all 7 wires,there are ony 4 ?

I need the blue electric brake wire
I need the reverse wire
I need a power lead ( I assume this is a full time positive)

Were do I find these,I thought the blue one went to the back ?


any help would be great.

Well, since the first 2 go to yor tail lights, that might be a good place from where to begin tracing them. There is probably a dummy plug in your power distribution lock (under the hood) which, when replaced with an actual fuse, will supply +12v through the existing wiring. If not, run your own. Just be sure to fuse it.

Does that blue wire from the front go to the taillight brake light


I thought there might be wires back there caped off that I could use.

Yes and if you pull the tail light, all will become clear. Also, use a test light to make certain that you have the correct wire.

There may be. I have never torn into an H3. If you pull the tail light, you can trace your way to it. Again, use a test light to make certain that you have the correct wire. Questions are always welcome. Good luck and let us know how it goes.

Neat place to put the plug. I can recall in my avalanches and silverados nearly ripping them off since they hung down so low. You would think that hummer would have placed the plug in a similar place on the H3 as they did the H2
