biohazard Posted February 28, 2013 Report Share Posted February 28, 2013 (edited) Has the issue with the towing wireharness not being able to draw enough power to power the trailer lights been fixed in the 2013 DJ or do I need to talk to the dealship about fixing this ??? I have heard others having problems with thier trailer lights as the newer LED rear light harnesses do not draw enough power to power the trailer lights and they had to have their computer flashed to allow for more power draw, we will be picking up our new journey sometime int he next few days and was just wondering if i should be telling them about it before I pick it up...

alainbock Posted March 12, 2013 Report Share Posted March 12, 2013 Biohazard, I got mine done at a local auto shop that deals with car wiring and it works fine. Have it done by a professional is the only advice I can give you. Thanks, Alain Quote Link to comment Share on other sites More sharing options...
biohazard Posted March 12, 2013 Author Report Share Posted March 12, 2013 thanx... sounds like it was just a myth that i just heard, but yeah im going to have one installed by a shop, did the hitch on my 2010 and really dont want to do it again as it was a pain in the butt...lol Quote Link to comment Share on other sites More sharing options...
immjg Posted March 12, 2013 Report Share Posted March 12, 2013 you need an adaptor to convert from LED to your trailer wires. You will need to run a power wire to the battery. go to etrailer.com and check for your year they will have a kit like what is in this link. I have done this to my 2011 Crew and it works great.. http://www.etrailer.com/Custom-Fit-Vehicle-Wiring/Dodge/Journey/2011/C56154.html?vehicleid=201113912 Quote Link to comment Share on other sites More sharing options...
Woodsey Posted March 13, 2013 Report Share Posted March 13, 2013 If your journey came with the towing package...you might need to get the dealership to do a flash update so the module will work...that was an ongoing issue with the 2011 - it was not plug and go like promised.

biohazard Posted March 17, 2013 Author Report Share Posted March 17, 2013 just to update I was looking at the wire harness that came with my 2013 journey as we got the TOW PREP PACKAGE and noticed that the harness comes with all the necessary relays to bump up the power for the trailer lights. I think this was a flaw that was discovered when they first went to the LED lighting and corrected with this harness. Also the harness does not plug into the lights itself like my 2010 DJ but there is its own connection located at the rear of the car that bybass the lights all together. If i didnt have this harness it was going to cost me another 70 bux in parts to have the wiring done at a shop so if you have any possibility of wanting to tow the TOW PREP PACKAGE is well worth the money as you get all the proper relays along with the extra oil cooler... larryl 1 Quote Link to comment Share on other sites More sharing options...
dbrophy1 Posted March 17, 2013 Report Share Posted March 17, 2013 Good to know as I just ordered a 13 Crew and got the tow prep package Quote Link to comment Share on other sites More sharing options...
raff Posted March 26, 2013 Report Share Posted March 26, 2013 The wiring harness for the tow prep package was in the back of my DJ when I picked it up. I looked at the instructions which said you needed to pull,the rear fascia to install it. Crawled under the car to take a look, no need to pull bumper. Installation was 10 minutes, all clips etc line up with factory holes. Got the dealer to flash the computer when I brought it in for an oil change. Lights all work fine. larryl 1 Quote Link to comment Share on other sites More sharing options...

raff Posted March 27, 2013 Report Share Posted March 27, 2013 When I installed the harness I checked the 4 pin flat connector for the trailer and it had no power at any of the terminals. Dealer said the flash tells the computer that the harness is there and it basically activates the newly installed harness. Didn't charge me anything, had it done at oil change time.

wingit11 Posted March 27, 2013 Report Share Posted March 27, 2013 I guess I will find out this weekend. I will be installing the wiring and hitch this weekend. Spoke with the tech at the hitch shop and so far has not had to do a flash on any Journey and they have done several. Fingers crossed. :shades: Quote Link to comment Share on other sites More sharing options...
wingit11 Posted March 31, 2013 Report Share Posted March 31, 2013 Well; all done. Installed the trailer hitch that I dropped off of my old '09 DJ and reinstalled on our new 2013 DJ Crew. Bolted right up. Installed wire harness (T-Connector kit #761053) and all is good. Trailer lights work as they should. No need to have it flashed. Hardest part was routing the power wire all the way to the front and hook up to the battery. Would have been nice to have a hoist instead of jack stands and crawling around on my back. Other than that went very well. Quote Link to comment Share on other sites More sharing options...

dbrophy1 Posted June 18, 2013 Report Share Posted June 18, 2013 Hooked up my harness and hitch today but I guess I'm gonna have to get the flash done because I have nothing!! Quote Link to comment Share on other sites More sharing options...
Journeyman425 Posted June 30, 2013 Report Share Posted June 30, 2013 Hooked up my harness and hitch today but I guess I'm gonna have to get the flash done because I have nothing!I I ordered my 2013 Crew with the Trailer Tow Prep group, sales code AHT. We installed a Mopar hitch when the car arrived at the dealership and connected the supplied wiring harness to the wiring which was installed at the factory. No power to trailer harness. In order to enable the trailer harness, we had to add sales code AHC (Trailer Tow Group) to the vehicle configuration as per Chrysler, then reconfigure the vehicle to see the wiring installation. Tested wiring and all is working. Connected camper and everything works. Here is the document: LLC Version 1 Case Number: S1108000077 Release Date: 11/04/2011 Symptom/Vehicle Issue: Trailer Tow Wiring Is Inoperative Diagnosis: If vehicle has trailer tow group AHT and the trailer tow wiring harness is inoperative, you need to add a sales code (AHC). Repair Procedure: 1. Go to Dealer Connect, Service Tab, Global Claims System, Vehicle Option, Add a Sales Code and enter vin, then select “AHC Trailer Tow” and then select add, then hit the save button. 2. Now perform a vehicle restore configuration with the WiTech. Verification: Verify trailer tow wiring is working. Quote Link to comment Share on other sites More sharing options...
