How to Install a Brake Controller on a 2003 Ford F-350

Today in our 2003 Ford F250 superduty we're going to show you how to install the Tekonsha Primus IQ proportional trailer brake controller. This operates on of the 3 axials and part number is TK90160 we're also going to be using the pig tail, part number 3035-P for our factory Ford connection. Here's what our Primus IQ is going to look like once we get it installed. As you can see, nice easy to operate, easy to use style brake controller. We've got our manual override. It's right here. This is going to allow us to manually apply power to our brake in those emergency situations where maybe our trailer starts to get a little out of wack.

We'll just apply a little breaking force there and try to help straighten that out. There's going to be a nom 00:00:45 located right here on the side. This is going to control our gauge. Right now it says NC so there's NC, no connection. Let me go back and hook up the trailer.

When I do that it should show us a C, should switch from that NC to a C. We've got our C that come on, we're going to be in good shape. Now, as we operate that bar we're going to see the brake controller manually operate all the way up to our highest setting, which you see here is an 11 and we slowly real that down. We can adjust this depending on the size of our trailer. Also, road conditions, terrain and things like that can also come into play so it's really nice and set 00:01:28 that's adjustable up and down. We're also going to also going to have boost 1, 2, 3, and no boost.

There's a little red light here, that's gone off and we've got a B with no number. That means we've got no peak power that's going to go to our trailer immediately when we hit our breaks. Depending on the size of the trailer in relation to the truck. If we have a trailer that weighs less than our truck then we're probably not going to go with any boost but as that gets heavier and heavier and sometimes gets heavier than the actual truck itself we need to correlate that boost so it give us that immediate response so our trailer will get braking power all the way up to the highest setting that we have dialed in here on our controller. That's going to be for a second, maybe a second and a half, 2 seconds, it give us that initial boost. Then it reverts to what we've got programmed here to keep this nice and safe and stopping properly even in those emergency type situations. In this side we've got one dot.

This is going to indicate that we've got 12 volt power coming to our controller which is great. It says C here, which indicates we've go a trailer connected. It would say NC if we didn't. Finally, the other dot located right here on this outside is going to be for our boost, indicating that we are actually in boost mode. As you can see, when we go to boost 0 that light disappears. As we go to boost 1 it's right back off indicating that we've got it loaded. First thing first on our old Ford truck here we need to take off the fuse panel, kind of knee protector here. Just going to have some little twist fasteners you can use a straight blade screwdriver, a coin, your fingernail. We just want to turn those till they pop out and then that panel is going to come right down and out. With that out of the way, it's going to give us a great look here behind the dash board at our plugin. You can see here it's a little square grey plugin. It's going to have a tab on the side there. We can move it around a little bit. Now let's bring our harness up and around. We'll plug it right in. We'll push that in far enough, you'll here that little click. Give it a push pull, make sure it's connected. Now we've got our wiring run down here. It will plug right in to the back of our brake controller. We're going to go ahead and mount our bracket in place. With the superduties we've got a nice little pocket here that allow us to mount up and still stay within our angle that need. We need to be within 70 degrees of level. We won't be exceeding that there. Down here lower it gets pretty nice and flat, keeps it out of the way but still accessible. We're going to be using the plastic clip style bracket. There's also a metal U-shaped style bracket that you can use, really could be mounted where ever you want as long as you stay within the parameters. You can mount it up here but that's going to block off your access panel. We found this is just usually the best spot to get that put in. There going to 00:04:32 come with self-tapping screws. We'll just bring that right through our bracket there. Then right up into our dash, nice and easy. We're going to grab our pig tail. It'll go right into the back of the controller. What I like to do is just roll it over, see how that makes that little loop for us. That's going to allow us to tuck that up behind the dash. Backside of the controller goes in. We'll spread out our arms about the front side. There'll be a little noxious little click in there once you get it the right position. See right there, clicks in nicely. If we want to could spread those tabs a little bit. See how we bring that down a little bit, level it out some Nice setup, easily get to our buttons that we need to operate. No issues, no worries. Now, let's get that pig tail tucked up. All you're really going to need here is a zip-tie. Just going to bring that loop that we created right up here right underneath where we plugged in the pig-tail. There's a little hole that goes right through. We'll just take our zip tie through the little hole that we've got there around the pig tail. Let's tighten it down a little bit with our wire clippers, or side cutters or whatever. Turn that off. That will be up and out of the way if we ever need it. Snap that zip tie which is very easily accessible. We can pull down that access or do whatever service we need. Now, to wrap up our install we're just going to pop our panel back into place, wind those up. Let's give them a 90 degree rotation. That's all she wrote. With everything working properly that's going to complete today's installation of the Tekonsha Primus IQ, part number TK90160, also using the adapter pigtail, part number 3035-P, on our 2003 Ford F250 superduty. .
