Does this need a special wiring harness depending on the vehicle? For example, I have a 2004 GMC Sierra.

The DirecLink comes with a generic harness, but you can order a Tekonsha wiring harness part number 3015 for your vehicle with tow package for a direct fit.

Yes, you need a specific harness in addition to this kit. They are very inexpensive. That way it will just plug in to your oem trailer brake harness.

Probably not. They said it would fit my GMC Sierra but not even close. Not even the wiring adapter. Oh, and God help you if you have to return anything to these crooks.

No it doesn't come with the wiring kit, you can go to your local parts store and get everything to make a wiring harness

With the right wiring harness and mount, yes. But this unit only worked for me for a few months. Definitely not worth the money.

Yes it does come with a wiring harness. I found it helpful to have my cars wiring schematic to match the various functions correctly.

My husband installed it on our 2013 GMC Sierra 1500 with no problem. I don't think there's much difference between our truck and yours. We already had the factory installed wiring to the bumper and this allowed him to add an extra receptacle in the bed of the truck.

I am not an expert but I just installed one of these on a 2004 F150. My truck had the factory installed trailer towing package which included the factory trailer light wiring. Installation was simple because the factory trailer wiring has a plug that is specifically for a brake controller. I purchased the Tekonsha Brake controller and the Tekonsha wiring harness at the same time

This will fit the GMC Sierra. Its a far better connector than the stock unit.

The hardware is included but no wiring harness is included. You have to put a relay and switch to connect to the battery.

It all depends upon what year/model car or truck you have. Some just plug right in and others need a new wiring harness. Amazon should tell you if it's compatible with your vehicle. (I directly wired mine from the old harness to the new wiring on the back of the new unit.)

Will have to get vehicle specific wire harness for exact matching of wires. If you have an old clunker, just splice the wires in.

Comes wuth basic wiring. You might need some extra stuff depending on the vehicle. I would strongly suggest doing some research before jumping into this as a DIY project.

It worked on my 2002 Chevy Malibu so I'd say it should work on a 2002 GMC Sierra 1500HD. The manufacturer may have a list of compatible vehicles on their website.

This unit comes with a stereo specific wire harness. You will still need a vehicle specific wire harness to complete the installation.

No, I have a 2005 GMC Sierra which is has the towing package. You plug in the connection under the dash. I do believe that the tow package is fused.

It worked on my 2002 GMC Sierra. The dash lights were not working and this part corrected the issue.

No; I previously purchased this for a 2006 GMC Sierra truck. those plugs matched but most likely won't match yours because the truck build-models changed in 2005.
