How to Install a Wiring Harness for a Trailer on a 1998 Toyota Sienna

Today we are going to install part number 43475 from Hoppy. This is their wiring kit and we are going to install on a 1998 Toyota Sienna mini van. The wiring plugs for this T connector are going to be located behind the plastic here. You can either: a, access them behind the tail light or take off the tail light and get to them that way and run them straight down. Or, in this case, we are going to go behind the plastic and install everything on the inside. First off, we are going to go ahead and take off the thresh hold right here so we can take out the side panels. Alright, undo a couple of screws for the panels. Take off this panel here and there is an additional screw back here you can loosen the panel, the whole rear interior quarter panel with.

Alright, this is the gray connection right here. This is the one we want to take apart and the T part into it. It is real tight working, so you push down the tab here. I think you can pull off the bottom. We are working on the passenger side. We will install the green wire to there and then do the same thing back up in here. And then we can reassemble our panel at this point. We will repeat for the same thing on our drivers side here. We have to take out the jack assembly to pull this whole panel off because this interior part is connected to the plastic here. Again, the same thing applies to the other side. Just push in that little tab and it should pop apart. We will hide our box back behind the plastic and leave this little plastic end, the port for the 4-pole, we will leave that hanging out. We will go ahead an put our panel back together. And we can just reassemble everything inside this panel here.

Next what we are going to do is hide our green wire next to the harness underneath the carpet here and we are just going to pull these little tabs out, just tuck it behind it. Now what we are going to do is bond up our white wire here and our green wire to take up the slack. Now we will install our ground. And we will use the overlapping pieces of steel here. That way, you will have more steel to go through and more for the screw to adhere to. And our little converter box here, we can just tuck back up inside of here. And then, we will leave our 4-pole end port, we will leave that hanging out below the thresh hold. Now at this point here, you can simply just fold this underneath the plastic here and come up inside the jacks storage compartment. And then we can go ahead and plug our 4-pole into the port. And when you are ready to use it, you can simply pull it out, a little bit of it. Go ahead and put the door back on. And you have the excess hanging out and it will come down right down to your hitch. And there you have it for part number 43475 from Hoppy for a 4-pole T end wiring harness.
