Today in our 2008 Toyota Tundra, we're going to take a look at and show you how to install the Tekonsha Prodigy P2. This is a proportional trailer brake controller that'll work for one up to four axles. It's part number is 90885. To help with the install, we're going to be using the Tekonsha Plug-In Wiring Adapter, part number 3040-P, as well. Our Prodigy P2's a really nice, straightforward brake controller. It's very user-friendly which you'll see from the reviews, but it does a great job. This is a proportional brake controller so what that means is that it senses the deceleration that's in our truck, and it brakes our trailer accordingly.

Under heavy emergency stops, it's going to send that kind of power back to our trailer to get it stopped quickly. If we're more in the stop-and-go traffic or just slowly going down a hill and we need a little bit of braking force, it's going to do that for us. It brakes in proportion or in relation to how our vehicle's braking. The great thing about that is we don't have to wait for maximum braking force like we used to with the time-delayed systems. In an emergency situation, we've got our manual override lever here. This is going to allow us to apply the brakes to the rear of the vehicle right up to whatever our maximum setting is.

Right now I've got the gain set on high. It'll go all the way to 11. If I we're to bring the gain down, maybe only to about 4, 4.7, if I bring this lever all the way over, that's the only braking force I'm going to get. I'm never going to have to worry about reaching down here, grabbing this lever, and locking up the brakes on my trailer as long as my controller's set properly. For more hilly terrain, or heavier trailers, we want our gain to be set higher.

You can see we can simply roll this knob down, easily adjust that, down to a lower setting for maybe when we have lighter trailers or maybe flatter terrain. In addition to the gain adjustment, we can also set the aggressive or the intensity in which our brakes are going to apply on our trailer. Right now, we've got No Boost mode selected. We hit our Boost button here. We're going to see a b with nothing beside it come up. We can go to boost level 1.

That's going to be for a slightly heavier trailer in relation to our truck. Boost level 2, that's going to step it up just a little bit more. Maybe we've got a heavier trailer, more load on the trailer. Then boost level 3 is going to give us the maximum aggressiveness on that braking power being sent back. The P2 has a couple of other built-in safeguards. One of them is going to be to where in prolonged stops, or where our brakes have been applied for a long amount of time on our trailer, it's going to gradually reduce the amount of power being sent to the back so we don't have to worry about overheating them. It also has built-in safeguards to keep the electronics in our brake controller, our trailer, and our vehicle nice and safe. Another great thing about the proportional system here is that this can be mounted in any orientation as long as we've got it straight in line with our direction of travel. If the situation would require it to be mounted more upright, or maybe even turned down a little bit, it's not a problem for the P2. The first thing we're going to do here is to get our pigtail installed. It's a pretty easy process. Something I like to do, we've got an additional ground wire here. This is going to help give us an excellent grounding location. I want to do about maybe six inches from the end of it, seven, eight inches from the end of it. I'm just going to kind of tape it off to the other coil there, or the other loom that has the four wires in it. It's just going to help keep it neat when it's underneath our dashboard. We're going to look right behind the parking brake pedal here. Got a panel here on the side. If we go right above that, there's going to be a large white plug. You'll see right here, attached to the wire loom just behind that panel, that's going to be our plug, really easy to get to. Take our connector, slide it right on until we hear that click. Now that part's done. We need to find a spot for our ground to go. Conveniently enough right here we've got a stud. You see the ring terminal's just a little bit too small to slide on there, so we're going to be using one that's a little bit larger just by replacing that. Just going to snip that off and then you'll see, standard 10 to 12 gauge ring terminal. Put that back and just flex it over there, going to give us a really good spot to crimp to. A little pull to make sure it's nice and secure and th
