trailer brake controller

So this is a little off-topic but I can't think of anywhere else to put it.

Has anyone figured out how to wire a electric brake controller into the Cherokee with the tow package? I figure there are some wires under the dash somewhere, but I have not found them yet.

I'm not sure about the answer to your question John as I have surge brakes on my boat trailer. I always understood electrical brakes required the 7 pin connector and did not think anything else was required.

The following is what I discovered in the owners manual - hope it might help.

Towing Requirements – Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and sevenpin
wiring harness. Use a factory approved trailer harness
and connector.
NOTE: Do not cut or splice wiring into the vehicles
wiring harness.
The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
Refer to the following illustrations.

Next illustrations in the manual show 4 & 7 pin connectors and wiring connections.

Bill, thank you. but that does not discuss how to wire the brake controller. Normally they would prodvide 4 wires or a plug under the dash to hook the brake controler to. I could not find anything in the owner'a manual about it.

Electric brakes require a controller that actives the brakes on the trailer. This is not normally included on most vehicles.

The grand cherokee has a plug under the dash for a controller. I assume the cherokee does too. I'll see if I can find it and let you know.

My 06' Dodge Truck had a 4 wire connection behind the emergency brake. No splicing required. Proper pig tail was only $15.

Hopefully you will have better eyes than me. I have not been able to find one yet.

From Chrysler's wiring diagram database: There is a 4-pin connector in the usual location above the driver's footwell. I haven't personally gone looking for it yet, but according to their info, it's there.

Thank you. That is the first diagram I have seen that pinpointed its location. I guess I need to go back under the dash and look for it again. Looks like it is at the end of the large wiring bundle in the driver footwell.

Thanks to CDNTrailHawk I was able to find the plug for the harness tonight.

It is located behind the plastic kick panel in the drivers foot well.





You remove the screw and carefully pry the tab that is holding the kick panel in place from its bracket. The plug is on the firewall/wheel well behind the wiring. It is the grey plug you can see next to the metal bracket. That wire with the finned covering was in front of it and made it hard to find.

Acidsnow, CDNTrailHawk and eak like this.
