trailer wiring

hi all i bought a 2007 commander without a hitch or wiring to pull a trailer. i got a factory hitch from eBay but had to go to the stealer for the harness i got the 7 prong one put it on per the instructions and went back to the stealer to have the computer flashed...fast forward 2 months later went to get the trailer out of storage plugged in the adaptor from the 7 prong to the flat 4 of the trailer and nothing took back to stealer they charged 50.00 to tell me that they would have to take the harness off to tell me what is wrong. i am rather mechanically inclined and this was a plug and play set up unplug tail light plug in harness...run wires to the battery poss and neg left the break wire taped up under dash for future use. i have power at the 7 prong and i have tail lights but no turn or break lights any ideas thanks ed

which motor do you have? I ran into the exact same problem with my V6 and there are two seperate harnesses.... one for the 8's and a much more complicated one for the 6's. check out this link down towards the bottom. since then i have installed the other harness, and all works fine.

If the wrong harness was installed then the dealer will need to swap it at no cost, locate your invoice and let us know what part number you had installed.

Hey Forsale69....Did you have to cut your bumper too? I'm planning on installing the OEM stock hitch, but I'll have to cut my bumper and install the bezel for it too. Just wondering if you did.....How'd you do it?

Thanks.

If he got the factory hitch, which is what he said he got, then yes he had to cut the bumper. No way to do it without cutting the bumper.

Hi all, new to the forum. The dealer also sent the wrong harness to me, I read this link and called them back, they will have the correct one tomorrow. Thanks for the tip Forsale69!!

About how long does it take for the complete install, wiring harness, hitch and bezel? I have a lift available for me to use for about 2 hours or so...

Thanks
Robert

Help: Trailer Tow Hookup - No Power

I bought a used Commander w/o a trailer hitch and had the dealer install a hitch and plug for the trailer hookup.

I have no power at all at the hookup. The fuses are all OK.

Does anyone know if there is a plug somewhere that needs to be connected in the case when a vehicle is not originally equipped w/a tow package?

Any other ideas? I don't want to deal w/the dealer.

I think that the dealer needs to enable the harness with the Starscan.

Are you kidding me? I can't believe it has to be enabled.

Thanks for the quick responses and I'll take it back (again).
