I was thinking about installing a trailer hitch reciever on my 2009 H3 3.7L. Is there a factory wire harness available to ease the electrical part of the install, or do I have to scab into the tail lights. I want to install a 7 pin plug. What have other members done, and what do I have to be carefull of?
Thanks

There are plug in kits that go straight to your OEM factory harness. No need to splice anything. The aftermarket ones are much less than half compared to the Dealer ones.

If you have a plug, do what recon suggested. If no plug there should be a group of wires behind the left rear tire, tucked up under the vehicle. The wires are codes as....

Thanks F5... I was hoping there would be some wires allready ran back there, I just could not see them. I will look behind the left rear wheel well for the bundle. Since I did not have the OEM tow package do I need to add fuses in the box up front?
I was going to buy one of those hitch recievers from Curtis or Uhaul for around $250, but if I can get an OEM reciever and bumper that would look the best. Does anyone have the part numbers for what I would need to do a complete OEM setup? Or if someone had a wreck laying around that could strip off the parts and send them would be great also. I believe the parts would be the same for all years 2006-10?

Thanks again everyone

I just removed the bumper cover, slid a piece of heavy wall 2 inch square tubing into the pre-punched square holes in the bumper brackets and mig welded it in place.
Then welded a store bought 2 inch receiver onto the bottom in the center with some bracing and chain loops. I trimmed a nice neat square hole in original bumper and reinstalled after some paint. Its actually a little higher and forward than the oe setup. Added a flat four pigtail to the existing trailer wiring and done. Total cost in
materials was $30 including paint. When the drawbar is removed you don't even notice it. I usually have a pintle hook in it.

I finaly got an OEM tow bar from a fellow club member Frumaker. I just installed it last weekend and had to cut out a slot in my bumper. It looks just like stock ! I will post up some pics soon. I still have to wire in the plug this weekend. Found the wires stuffed up in the bumper with the wires going to the lisence plate light.
Anyone interested in the OEM bumper mounts that slide in the frame rails? They can be made into a tow bar if you do like Reloader said and weld in the parts. Otherwise they will just be sitting in my garage next to the other original parts I have taken off.
