Trailer Wiring Harness Installation - 2000 Mercury Grand Marquis- Video
Today on our 2000 Mercury Grand Marquis we'll be installing the Tow Ready Circuit Protected Module Light with Four-Pole Harness, part number 119179KIT. To begin our install we'll first need to hook up our new module light and wiring harness. To do that we'll need to locate the manufacturer's wiring that runs to the rear taillights. To do this we'll go ahead and remove the four push pin fasteners securing the rear threshold. Next we'll go ahead and remove the rear threshold and sit it aside. Now by the removing the plastic hold down fastener for the carpeting we can peel back the carpeting along the threshold and behind the driver's side taillight assembly. Here we'll locate the wiring that runs to both taillights. To access the wiring we're going to go ahead and use our utility knife to cut back the electrical tape and cover and remove it so that we can use our test light to probe each wire to locate the running light, turn signal and brake circuits. Now for this application it's a combined setup so the turn signals will also act as the brake light signals. more
