How to Install a Trailer Wiring Harness on a 2003 Cadillac Escalade

Today on our 2003 Cadillac Escalade, well be installing the Hopkins Custom Fit Vehicle Wiring 7 and 4 Pole, part number HM40975. This will be in conjunction with the Draw-Tite No Drill Mounting Bracket, part number 18136. First lets go ahead and identify the manufactures wiring that well be using. As you can see, its bundled up here behind the bumper against the frame. Well go ahead and untie it and run it down to the hitch. Now for this application we want the wire to go over the hitch, so Im going to go ahead and loosen up the hitch enough to get the wire connector over the top of the hitch and between the bumper.

After weve re-secured the hitch to manufacturers specifications, we can go ahead and install the universal mounting bracket using the cable clamp provided. Now with that in place were ready to go ahead and install the bracket and connector. Well be installing the bracket using the self-tapping screws provided with our install kit. Now with the bracket mounted, well feed the wiring harness through the bracket and connect it into the back of the 7 and 4 pole connector. Now with the connection made well pull on it just to make sure that we have it locked into position and then well lock the connector into the bracket.

With that our install is complete. There you have it for the install of the Hopkins Custom Fit Vehicle Wiring 7 and 4 Pole, part number HM40975 in conjunction with the Draw-Tite No Drill Mounting Bracket, part number 18136 on our 2003 Cadillac Escalade. .
