Today we are going to install part number 118366 from Tow Ready on a 2000 Ford Windstar. To get started, what we want to do is go ahead and lift up the tailgate and start taking off the passengers side tail light. Okay, the connection points are going to be on the gray connector here and the black connector. The green one is for the reverse light lead, and we will have nothing to do with that. We have got a lot of wires to hook up, so we are going to do it one step at a time. First off, we have got our 4-pole here, which will get run through the grommet to the inside and be stored by the jack storage compartment when we are not using it. But for now we are just going to go ahead and just tuck it down in the cavity here, just to get it out of our way. Next, this is the yellow wire this is what goes over to the drivers side of the vehicle.
So what is going to happen here is that this is actually going to be routed out to the other side. And all that is going to do is come out to the side, come out here, and then back over, underneath the bumper fascia. So we will just keep that out of our way for now. And these extra wires here, this is a ground screw - that is going to get grounded to the body of the vehicle. And then also, there are two other leads here. The red lead will not be used, so the only thing that is left over is our blue wire. And this one gets run straight to the battery. We will put that out of our way, too. So, we know which wires go where we will start making our connections to the tail light.
The lead with the green wire is going to go to our turn signal circuit, which is going to be yellow here. Okay, we will go ahead and disconnect the lead for the turn signal. Pop it off, and pop the new one back into place. And then the other half, we will plug back into the factory wiring harness. And there are a lot of wires here, but one step at a time, we will get through it. All right, and the next wire here has a brown and red. Brown is for the running light, and the red is going to be for the brake signal. And that is going to go to this circuit here for running light and brakes. So we will take this one apart, plug one half in, and plug the other half into the wiring harness. So, our connections to the tail light are done. Go ahead and just put this back down, out of the way. Next what we will do is go ahead and run our 4-pole into the jack storage compartment through this grommet right here. So what we are going to do is pull off the grommet and what we are going to do is just put a slice right through here. Our wires will fit right in there, and then we will just push it back into the jack storage compartment - as much as you can, all the way out. Leave a little slack in the wire, and then go ahead and tuck the wire back in, just like that, and then go ahead and just reinstall the grommet.
Next we will go ahead and attach our ground screw, pretty much right straight to the body. To run our power wire out the bottom, we will just go ahead and drill a hole through the sheet metal here, and then just install a simple rubber grommet. Now we will run our power wire up through there, up to the module. We will hook up our black wire it is going to get run up to the battery, to our blue wire, which is labeled 12 volt from battery. Okay, we are back to our yellow wire. Again, what is going to happen is this we are going to run it out the bottom of the tail light here and then back, underneath all this plastic fascia all the way across. So what we will do is pull this off to the side and just kind of tuck it in for now, just like so. Next we will take our Modulite box and just attach it to the sheet metal behind it, and then we will go ahead and put our tail light assembly back into place. To get underneath the bumper fascia, we are going to have to take out all these little screws going across here. And what we are going to do is tuck our wires right behind the fascia. And when we put it back together, the top edge of the bumper fascia will hold the yellow wire in place going all the way across. Once we have got all our wires run all the way across, we can go ahead and reinstall the screws. Let us go ahead and take off the drivers side tail light and make our connection behind that. Again, the connection point that we want to make is right behind the turn signal circuit. We will pop that off, and make our connection. All right, once we make our connections, we can go ahead and reinstall our tail light.
Trailer Wiring Harness Installation - 2002 Ford Windstar

Today on this 2002 Ford Windstar we are going to be installing wiring harness part number 118366. We are here at the rear cargo area of the Windstar, we want to locate the ports that we need to plug our wiring harness into. These ports are located directly behind the tail light assembly on both the driver and passenger sides. The first thing we are going to do is remove the tail light assemblies. To do that we have two Phillips head screws at the top of the tail light that we are going to remove. With those two sides removed we also need to release this inside clips that are holding the tail light assembly on. There is one on the outboard side and one on the inboard side at the bottom. And then starting on the passenger side, we are going to start plugging the harness in line. On the passenger side we are actually going to be using two of the plug ins here. Using the top one and the middle one. If you look at the harness you can see on the short side of it you actually have two sets of connectors that are color coordinated to match the connectors on the vehicle. 1:09
