Trailer Hitch Installation - 2001 Mercury Grand Marquis - Curt

Today on this 2001 Mercury Grand Marquis, we'll be installing Curt hitch, part number 13707. Now we've gone ahead and held the hitch up into place using it as a template to spray paint where our mounting points will be. Now we'll use a stent drill process to drill up through our half inch hole that we need in our frame. The hole closest to the bumper needs to be as close to the center of the vehicle as possible. We'll use a center punch to mark the hole within our template at all four places that we'll be drilling. Now with all four of our holes drilled, we can use our fish wire to fish through the forward most mounting location towards our access hole here in the frame.
Trailer Wiring Harness Installation - 2001 Mercury Grand Marquis

Today on our 2001 Mercury Grand Marquis we'll be installing the Tow Ready Wiring Kit, part number 119176KIT. To begin our install we'll need to remove the rear threshold in the trunk. After removing the threshold we'll need to pull off the clip holding the carpet in behind our tail light.With the clip removed we'll simply peel the carpet down exposing our wiring here on the driver's side. We can use the test light included with our hardware kit to locate the signals we need for the harness. We'll simply back probe the connector to locate our signal.We can undo the tape exposing the wires a little farther back on the harness. Now we've determined that the brown wire on our factory harness is our tail light signal, the green wire is the left turn signal, and the orange with blue tracer is our right turn signal.
