Need to find where to plug brake controller harness in to OEM harness

Yup! All those are right. REPLACE BOTH TAIL LIGHT ASSEMBLIES. (N.A.P.A. OEM Parts Only)...Easy (a little removal of the tail lenses...They plug right in. "Plug & Play!"

There usually is an open harness plug under the dash. When you buy a brake controller, the instructions should come with it. The better units will have a pigtail which will plug right into the other half of the open harness plug.

If the kit you have has the pigtail connector, but loose wires needing to be connected, see if the color of the wires match those on the open connector. Then match the color of each wire.

Some years of trucks will have a heavy duty flasher to install in the Powerbox to accommodate the extra trailer lights.

iguess you tryed removing this OEM PLUG TO SEE IF THINGS RETURN TO NORMAL?or you can just diconnect power supply to plug to see if there is problem,next use test light when connected with power to plug and see if tester will blow fuse ,it allmost sounds like there is a direct short to ground look over wires carefully look for problems and the plug .hope you get it good luck.

Ford's factory supplied brake controller harness end can be found loosely stuffed under the dash, usually just above the driver's right leg. A Ford harness has a rectangular shaped connector.
Simply connect the brake controller harness connector into the vehicle connector. Zip tie the harness wires to another harness to prevent the wiring from hanging down near your feet.
I hope this helps.

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

easiest way is to also buy the wiring adapter almost all elect brake units sell a vehicle specific wire harness that u unplug brake wire harness plug in other harness than plug in brake harness and just connect the wires to elect brake controller eliminates cutting and splicing ur brake harness about $18

most new trailer brake units dont splice into the lines anymore they have vehicle specific plug that connects in line with brake harness under dash or under hood

Brake controller should plug into the rear lights.

i know this worked with my 99 navigator 32 valve used a viper car starter.
