Tow/Wiring Question

I just got a trailer with electric brakes, I have a 2012 JK w/towing package. Has anyone installed the Genuine Jeep Accessories 82210214AB Trailer Tow Wiring Harness? I was wondering if I could keep the 4 pin and what is the gauge of the wire? I am installing the Tekonsha 90195 P3 Electronic Brake Control to control the brakes on the trailer. thx Jim

I would not tamper with the OEM 4-Flat Wire Receptacle. Install the optional 7-Wire Receptacle Wiring Kit as per the step by step instructions as a stand-alone unit. Be prepared and have plenty of patience. Also be certain that the brake controller is suitable for a four brake system.

4 pins with brake control ? I don't think, a 4 pin adapter is only +/- 10 bucks.

If I remember I used 10 gauge.

You can remove or keep the 4 way harness... It plugs in exactly how the 7 way harness will and just piggy backs off the factory harness just as the 4 way does... You can still have them plugged into each other at the same time with no issues.

Route it exactly how they show in the instructions and you'll come out with the perfect amount of wire to hook up at the battery...

When you hook the brake controller up to the battery, use a self-resetting circuit breaker. NOT a fuse...

I installed my harness without a lift... I was completely stock and able to get under and route everything just fine... When you get to the front of the vehicle, you may run out of places to tie the harness to... Keep it away from the exhaust and any fluid lines and you'll be fine...

thx everyone, yes Michael347, the 4-pin will not, I purchased the optional 7 pin harness frm Jeep (http://www.amazon.com/gp/product/B00...ilpage_o00_s00) and Brake Controller (http://www.amazon.com/gp/product/B00...ilpage_o00_s00) and ckt breaker (http://www.amazon.com/gp/product/B00...ilpage_o00_s00). I just wanted to know the gauge of wire if someone already had installed the Jeep 82210214AB Trailer Tow Wiring Harness.

I want to say it's a mix... Which wire were you thinking of specifically and what are you doing? All the wires should be good to go and not have to do ANYTHING really except wire up your brake controller, which I would use 14AWG...

14 AWG is really the minimum I would use, usually they say 12 AWG for single axle and 10 for dual axle.

12 is what was in my fifth wheel add on harness for the F250... most fifths are dual axle if not dual braked - so would expect they anticipated this?

I guess I am just lost as to why he needs to know the gauge wire used because everything needed is right in the harness if he is indeed using the Mopar one... No need to add anything anywhere except for running power to the controller....
