Electrical problem
2008 Hummer H3 6 cyl Four Wheel Drive Automatic

I want to install a trailer brake control on this vehicle. I have found the wires that connect to the brake control under the dash, but I cannot find the blue wire that goes to the rear to hook to the trailer plug. This vehicle did not come with a trailer hitch or trailer plug. Thanks

Since it did not come with the trailer package. You will have to run the blue wire all the way to the rear.
