How to Install a Trailer Brake Controller on a 2001 Chevrolet Silverado


Today with our 2001 Chevrolet Silverado, well be installing the universal installation kit for trailer brake controllers part number ETBC7. In conjunction with the ETBC7 kit, were also going to be installing the Tekonsha Prodigy P2 Brake Controller part number 90885, as well as the Tekonsha Plug-in Wiring Adapter for GM vehicles part number 3025-P.Im going to first begin by mounting the bracket that holds this 4-and 7-way plug. Were going to mount it here to the underside of the bumper. With our bracket held up into position, well go ahead and take a paint marker and mark the two holes that well need to drill out.With our two holes marked, were going to need to take a drill bit and drill out both of these two locations so that we can mount the bracket. Then add a couple screws to hold it in place.Next, were going to need to mount the plug to the bracket. Go ahead and slide the wires to the opening here, line up the holes in the bracket with the plug and were going to add the screws.

The back side of the screw, well put a locking nut. Well go ahead and repeat the same process for all four of the holes. Now that we have all the hardware installed, well go ahead and tighten it down.Next, were going to go ahead and connect the four pull 02:01 thats on the back of our plug with the four pull 02:02 that was already on the vehicle. Before we do that though, were going to add a little bit of dielectric grease to the connection here. Thats part number 11755.

Now that we have our grease in place, go ahead and make our connection.Once our four pull 02:26-ins are plugged together, were going to add a zip tie through here and here to make sure that it stays nice and tight. Now that we have a zip tie pulled down, well go ahead and cut off the excess as well as these little cover here as we wont need that anymore.Next, were going to need to connect our duplex cable to the black and the blue wire on the back side of the plug. Go ahead and strip back a little bit of this gray protective covering to expose the white and the black wire.Next, we need to go ahead and strip back a little bit of wire on both. Then, go ahead and connect the black wire to the black wire using the butt connector thats already on the black wire on our seven pull 03:24. Once thats in place, well go ahead and crimp it down.

Were going to connect our white wire to the blue wire again, using the butt connector and crimping the wire down.Now, the purple wire is for the backup circuit or the reverse light circuit. Here on the factory wiring harness, there is a tag up here that shows that the light green wire is the backup circuit. Well go ahead and connect the light green wire here to the end of the purple wire using the butt connector. Next, well go ahead and use some electrical tape to tape up the butt connections.Next, were going to go ahead and install the wire loom that comes with the kit to give our wires back here a little more protection. We also went ahead and added some electrical tape to help keep the wire loom in place.

Now, well go ahead and route our ground wire over to a location on the frame but well be using a self-tapping screw to secure it.Next, were going to go ahead and take the end of our gray duplex wire and feed it up into the frame rail here and start to pull it forward. Well go ahead and pull all the slack out of it so we can secure the rest of the wires here at the rear of the vehicle using a few zip ties. You want to make sure that when routing your wire up towards the engine compartment, you keep the wire away from any areas that may become hot, have sharp edges or have moving parts as all of these could easily damage the wire. Can secure the rest of the wires using a few zip ties.Now, well go up here into the engine compartment where well finish pulling our gray duplex wire up here near the fuse box area. Go ahead again and secure the wire with couple zip ties. Next, were going to need to take the cover off the fuse box here. Simply lift up here on the edge, set it aside for now, then were going to need to take the four bolts out that hold this bracket in right here. Theres two up here as well as two here underneath the piece of weather stripping.Now, were going to need to remove the rest of the plastic cover here around the fuse box. Theres a couple tabs down here on this inner side that well need to pull out so that they release the tabs. Go ahead and pull out gently on the fuse box cover, all tabs released, remove the whole plastic cover from it.Next, were going to go ahead and cut our duplex cable to length. Were going to need to make it to this stud right here with the black wire and the white wire, well be tying in with this blue wire over here. Well go ahead and trim it off about right here. Well then need to go ahead and trim off some of the gray of the jacketed part here to expose both of the wires. Well simply use our razor knife and put a slice along the edge of it and peel it back.Well go ahead and take the black wire, strip back a little bit. Well be adding a ring terminal to this side. Once our ring terminals in place, well go ahead and crimp it down. Well then be connecting it to this hose or this stud right here. Go ahead and slide the ring terminal over this post right here and then you will need to supply the nut that goes on top of this. Well use the 8mm nut with a 1.5 inch thread pitch to secure cable to the post. Go ahead and tighten the nut down.Next, were going to go ahead and trim this little connector here off of this blue wire as well be using a butt connector to connect the blue wire to the white wire. Well strip back a little bit from both the blue and white wire and then let our butt connector in and crimp it down.Lets go over real quick what each of the different colors are for. This black wire here is connected to the left side post here or the forward post, thats for your 12-volt HUD 09:23 or your auxiliary port back on the 7-way plug and the white wire is what is the brake signal wire going back or essentially the blue wire so thats why were tying that in with the blue wire upfront here.Youll also notice that theres a red wire here and this red wire with the ring terminal already connected from the factory, well tie in with this port over here. Thats what gives the port inside the cab of the vehicle power when we tie in for the brake controller. Well need to add this to this port right here and again, youll need to supply a nut to tighten it down. Well go ahead and put our nut on and then tighten it down. Well use the 8mm nut with a 1.5 inch thread pitch to secure cable to the post.Next, were going to need to install this 30 amp fuse in this location right here. When you add the fuse, itll make the 12 volts apply back at the rear of the vehicle hot.Next, well go ahead and tape up our butt connection here to give it a little more protection. Now if thats done, well go ahead and reinstall the covers on the fuse box as well as the support bracket that goes right here. Now we can go ahead and put our fuse box cover back in place as well.Now, well go ahead and cut off any excess zip tie to clean up our install look. Well go ahead and follow the wire back to the rear of the vehicle cutting off any excess zip tie along the way.Now, were here in the cab of the vehicle. Here on the driver side, were going to need to remove this cover here and underneath it, theres another fuse panel. To remove the cover, well need to remove this plastic nut here in the center. With the nut removed, we can go ahead and pull the plastic cover off.Heres what the pigtail looks like that well be tying in. There is a wiring harness that allows you to tie directly into the vehicles wiring harness and then go to the back of the brake controller. Well be taking the brown end here and connecting it with this port right here in this fuse box. You want to make sure that you push the plug all the way in so that the locking tab grabs. Now, we can go ahead and put the plastic cover back on as well as the plastic nut.Now, with our cover back in place, next well go ahead and choose a location to mount our brake controller. Go ahead and use the two screws that come with the kit in order to mount our plastic pocket here on the lower section of our dash.Now that we have our plastic pocket mounted, well go ahead and route our wiring harness over to the plastic pocket. Now, well go ahead and take the end of the wiring harness and plug it into the back of the brake controller. When pushing it in, we want to make sure that the locking tab on top is fully engaged. With our connection made, we can go ahead and slide the brake controller back down into the plastic pocket and then we use a couple zip ties to secure our wire up underneath the dash.Once our wires secure, well go ahead and trim off any excess zip tie to clean up our install look. With our trailer plugged in, youll notice that theres a C on a read out screen on our brake controller that tells you that your trailer is connected. When the trailer is unplugged, you get an NC telling you that the trailer is not connected properly.Now, this bottom lever here is the manual override. The knob here on this side is what adjust the power output and this little button up here on this side controls the boost feature or how aggressive the brakes come on.That will do it for the installation of the universal installation kit for a trailer brake controller part number ETBC7. In conjunction with the installation, the Tekonsha Prodigy P2 Trailer Brake Controller part number 90885 as well as the Tekonsha Plug-in Wiring Adapter for General Motors vehicles part number 3025-P on our 2001 Chevrolet Silverado. .
