Hello - I have a new dodge journey sxt (2014) we bought in November.
I installed a hitch myself (which is too easy) and realized that there is a plug under the rear bumper to stick in an "OEM" harness to get the 4-way plug. I purchased it from the dealer the other day ($128.00 plus taxes). They told me that if I installed it myself, there is no refund of warranty. I went under the car, and could not even get my thick hand in the area to remove the protective plug to even attempt to plug in the harness.
Anyway, I paid the dealer today to put it in for me (40 bucks in and out in less than half hour) but I had my wife go and get it done.
I come home tonight and give her a test - I have several light testers and even a volt meter. Plugged it into BOTH of my known working boat traielrs - nada. Not even a climps of a volt going through this newly installed brand new harness.
I'm a bit pissed off that these guys probably did not even TEST the freakin' thing, but I'm starting to wonder - since this is a new car, would the computer have anything to do with this not working? Like it's brand new - the car is new, the wiring is new.... do they need to turn this on in the computer?
Any info would be greatly appreciated!
also, I the LED tail lights - which probably doesn't matter unless you're putting in an after market wiring harness.
