How to Install the Curt T-Connector Vehicle Wiring Harness on a 2020 Chrysler Pacifica


Today, we're going to be going over and showing you how to install the Curt T-connector wiring harness here on the 2020 Chrysler Pacifica. The only thing we're going to be able to see from this kit here is the actual trailer connector. Now there's a couple of different means of attaching this. We can purchase a series of brackets here through etrailer to permanently attach it to the hitch tube. However, we can just use the included dust cap to loop it around the safety chain loops which is going to be the most economical option. So if you're going to be towing a trailer with your Pacifica, you will need a trailer wiring harness.

It's going to allow us to remain legal while we're towing out on the road letting those behind us know what we're doing. So this one here is going to be the most basic one. It has a four-pole flat connector which most trailers are going to use. However there could be certain trailers that are a little bit heavier. They have electric brakes.

In that case, you're going to need a seven way. And we do offer adapters here at etrailer that allow you to use this four way with the seven way adapter for the four way flat, the basic signals. It's going to carry over the vehicle to the trailer. That's going to be the stop and turn signal circuits for both the left and right-hand side as well as the running light circuits. Now, if you have any other circuits such as a battery charge line or the electric brake output that's when we would need a seven way.

So obviously towing going to be the main use for our trailer wiring harness but there are some other applications you may not be aware of, such as cargo carriers with built-in lights. We're going to be able to utilize those using the four way. So the great thing about our kit here it actually has a powered module. And what this means is it's going to draw power for the trailer lights from the vehicle's battery. So we don't have to worry about it.

Drawing from the taillight circuits on the vehicle and creating any issues. Furthermore, we have the powered module but we also have integrated diodes in each circuit. And what this does is it prevents any electricity from backfeeding. Therefore we don't have to worry about any issues with the trailer wiring affecting our vehicle. So in regards to installation it is going to be plug and play. We don't have to splice into any of the vehicles wiring. Therefore there's going to be little to no modifications needed. It's definitely something I think you guys can do at home by yourselves. Let's go ahead and walk you through this process now. We need to open up our hatch here. We're going to be removing the passenger side Taillight we'll need a T30 Torx bit. There's going to be two screws inside here. and so we have those screws out. We can pull our taillight out and a way. We have one connector on the back here. See on the bottom, we have that red locking tab, press that away, depress the center, and then pull straight out. I'm going to take a piece of pole wire. We're gonna feed it down through this pocket here try to get out to come underneath. And then what we're going to do is tape our connector from our wiring harness to the pole wire and then pull it back up into the pocket here. So we've got our connectors up where we need to be inside the tail light pocket here. Now it's a pretty tight fit behind the bumper. There there's really not much room for these things. So if you want to save yourself a little bit of trouble you can actually just go ahead and cut this wire and then easily pull that one up through there. Just make sure you reattach it. Preferably using heat shrink butt connectors. Like you can see we have here. Now that we have our wire up here I can go ahead and just simply plug it into the factory taillight connector. It'll only go in one way. So now that we have our connections made we're going to go ahead and reinstall our taillight here. You may need to tuck these down back behind the bumper there in order to have room to re-install the tail light. Now that we have the taillight back in place I'm just going to re-secure it using our factory hardware. So next we'll need to go ahead and remove the driver's side tail light. We're pretty much going to be repeating a very similar process. We'll take a piece of a pole line. We're going to tuck it back behind the bumper there. And then once we route our connector over to the side there we can pull it up through the opening. So Indistinct riding our green wire attached to the converter box over to the driver's side of the vehicle. You're only going to get about halfway here. So these next couple of steps may vary. Now, if you already have your hitch installed then you're probably going to have a little opening here. That's going to make things a little bit easier for you to work, but if not we're going to have some screws here along the underside of this panel. We're going to have to remove those. It's going to take both a 10 millimeter and an eight millimeter socket. And we're just going to peel this down to give ourselves some more room to work. Cause we can only get about halfway here with our converter box before we run out of our green wire. So what we need to do now is we need to actually Mount the converter box. And what we're going to do is we're going to pull back this panel and we're just going to Mount it to the underside of the body right up in there. So in order to actually attach it we're going to use two methods. We're going to use the double side the little foam pad that they give you in your kit. We're also going to use a self tapping screw. So we're just going to find a nice flush surface up there that we can place the converter box on. And then we'll come back with a self-tapping screw and secure it with that slot there on the end. Okay, so now we're going to take a couple of zip ties or a ring clamp and secure our green wire here. So it doesn't fall down and contact our exhaust. The next thing we're going to do is secure our ground wire. Now, if you used one of the self-tapping screws to attach your converter box you'll need to source an extra one here for the ground but we're basically just going to Mount it on that same surface there on the bottom of the body. So now for our yellow and Brown little harness here we're going to be routing this up behind the driver taillight pocket. So we're going to do the same thing we did on the other side. We're just going to go ahead and cut these to make it a lot easier to get up in there. But once we have them cut we're going to route them over the trailer hitch here. You can see we have our pull wire pulled down. We'll go ahead and tape those up to that so we can pull them back up in the correct position. So now don't forget to reattach our wires here to our connectors. Again, we're going to be using heat shrink butt connectors but once we have these on and sealed up we are going to go ahead and reinstall our taillight. So now the last two things of our installation, number one we need to secure the trailer connector. So we can actually fix this permanently to the hitch using a series of brackets, which we sell or we can just simply wrap it around the safety cable loops here using the included dust cap. So that's what we're going to be doing. Just make sure you tie up all your excess wires. And then we're going to go ahead and route our power wire to the front of the vehicle. We're going to go ahead and do that now. And then we'll show you the path we took. So we've already got our panel button back up or a power wire is basically going to run down diagonal across here, the corner section here where we have an opening right behind the wheel well and then we have the wire coming out of there up and over our sub frame. We have to jump over a couple of the cross members until it's going to come out in this area here. You can actually see our wire here but it's basically just zip tied to the brake lines. And that's how we have it routed to the front. So we just follow the brake lines all the way down here went ahead and just slightly remove this panel here. You don't have to remove all these fasteners but there's a few of these nuts on the outside. You'll take a 10 millimeter socket and that'll allow us to tilt this panel down. And the brake lines are going to be up underneath this panel. We're just going to simply zip tie them to that working our way, all the way up to the front of the vehicle. So in this area here we went ahead. You can see our wire, but we went ahead and attached our wire to a pull wire. And then we just shoved it up through there. And we went up top to pull our wire the rest of the way through. So once we have our wire routed up into the engine Bay here I just like use a zip tie, tie it to something to stop it from falling back down. So the next thing we're going to do is we're going to be removing this little intake for our air filter. So it basically just sits into place like so and we'll just pop it out. There's these little tabs here on the bottom. So it's pretty easy to slide out but then once we have access to the battery we're going to flip over this little red cover here and this is going to reveal the terminals. Now we're going to be splicing into one of these in order to attach our power wire. Cut off the excess power wire here we're going to grab our inline fuse holder and then we're going to splice that onto that power wire. And then the other end is going to have the ring terminal which will attach to our battery cable. Now let me go ahead and route this under the air box bridge there. Now we can just simply go ahead and attach it to one of the studs on our positive battery post. So now once we have our positive lead detached we are going to insert our fuse, and then we can test everything out Now with our four pole tester hooked up we can make sure everything works. Now we do recommend using one of these but you can use your trailer as well. So we have our brake lights left turn right turn and then finally our headlights. And that's going to do it today for our look and installation of the Curt T-connector wiring harness here on a 2020 Chrysler Pacifica..
