Look in your users manual that came with you Yukon. If it has provisions, you should be able to locate this wire harness just below steering column or alittle to the right.(they at least give you room to get in so you dont hit your knees, where they usually mt. it.) Good luck, best regards.

2007 Yukon Xl Denali can the headlight switch/dimmer cause only the tail lights to not work. Dash lights, signals, brake lights when pressed work. Both sides went out. No blown fuse or broken wires.


If front park lights are working highly unlikely headlight switch is the issue. Is the vehicle equipped with a trailer towing package and wiring to the rear? I would start there. This vehicle may also have a taillight module located under the vehicle on the passenger rear attached in the wheel well area that goes bad

I have a 05 Denali XL 6.0 and i can't find the trailer brake harness under the dash. Please help!!


Hi, the provision for the electric brake controller is located in the electrical center , just to the right of the parking brake. There is a plastic nut, that holds the cover on, and beneath this cover are ports where a connector may be plugged in. A factory harness must be obtained from a Chevy, or GMC dealer for the install. This harness will be labled with wire locations, as it will be attached to your brake controller, then plugged into the slot in the upper l/h corner of the electrical center. The plug will only fit in the appropriate slot. You will then need to put the provided J- fuse into the underhood fuse block. Tis should be the only missing fuse. You should be well on your way, after these few easy steps. Good luck...Coop

2008 GMC C5500 factory wired for trailer harness (7 pin). I just purchased brake controller and am trying to find where the controller harness plugs into the truck harness. Looking under the dash. Plug...


You are probably going to find four wires together that do not have a plug on them. There should also be a tag taped on the wires showing that it is for the trailer. You will have to put a plug or some kind of connection on those wires.

When i hook my trailor's lights to my 2003 yukon xl, park lights doesnt work, but all other lights work


You mean the truck parking lights dont work, or the trailer running lights dont work? Does the trailer just have tail lights or does it have front and rear side markers? I think you mean the trailer lights. Check for power at the plug,(Brown Wire) if there is power, then you could have wiring problems, but a better description of what works and what doesnt work needs defining.

Looking for plug under dash to hook aux trailer brake controler


The connector is located under the dash on the left side of the steering column. Their is a box, remove the cover and starting from the top left the second connector location moving to the right is the one to hook into, make sure that you have the correct wiring harnass adapter for the vehicle, their are two different ones for GM trucks. On the inside of the cover is also a diagram of the lay out of the box.
