Trailer and Vehicle Electric Winch Wiring Kit, for up to 16.5K Winches

Video Transcript for Superwinch Electric Winch Wiring Kit Installation - 2004 GMC Sierra

Today on our 2004 GMC Sierra well be installing Superwinch trailer and vehicle electrical wiring kit, part number SW2008. First note well be installing our wiring with the preexisting or installed winch. The first step of our installation is to take the 30 inch black wire with our install kit. It has ring terminals attached to either end. This will be an additional ground going from the battery to the frame or engine block of the vehicle. For this application well be taking it to the frame.

However, before we can attach it to the battery, because it is a side post mounted battery, well need to put on battery terminal extenders. Well be doing this for both the negative and positive terminals. Well be using the Deka battery side bolt extender, part number DW05416 for both the positive and negative side terminals for our battery today. To install the battery terminal extender well simply go ahead and remove the negative battery cable first. Then well go ahead and remove the current battery terminal hold down.

Next well take our new one and slide it into place into the negative terminal. To judge the length that well need well go ahead and reconnect the negative battery cable. Well take the new 30 inch wire and feed it over the terminal extender. Note with this application, the ring terminal is not large enough so go ahead and take a drill bit to resize the ring just large enough to go over the extended terminal post. Then we can go ahead and secure it with the nut and finger tighten at this time.

Then well route it down to the frame. Using a self-tapping screw we can go ahead and attach the other side of the wire, again with the pre-attached ring terminal, directly to the frame. Now well go ahead and take a zip tie and secure the excess wiring. Next well move to the winch, and in this application will be our rear mount. To use the Superwinch coupler well need to remove the current manufacturers power and ground.

Starting with the power, well need to go ahead and remove these two screws so we can turn over the power distribution box. Here we can access the four screws to remove the lid. With the lid off we can see the power wire running in that would be connected to the battery. To get a little easier access to it, well go ahead and remove the wire on top first by removing the hold down nut and then the wire. Next well go ahead and remove the hold down nut for our positive battery cable wire, and then remove the wire. Now were ready to go ahead and install the new Superwinch coupler. Checking the connection or coupler well see its indicated for both power and ground. Well go ahead and route the power cable into the distribution box. Note this application, the plastic grommet is not large enough so well have to resize it so we that we can fit the cable into the box. Well go ahead and remove it, set it up in a vice and then enlarge it with the drill bit. Now were ready to go ahead and install it. Well put our cap over the cable, then feed the bushing though. Then well go ahead and feed the wire into the power distribution box. Well install the plastic nut and then put the ring terminal over the post and resecure it with the nut. Now well go ahead and reinstall the bushing. We can go ahead and reinstall the wire we removed earlier for easier access. Now with everything resecured well go ahead and reinstall the lid and reattach the power distribution box. Next well need to go ahead and remove the ground cable. On this application its located at the bottom of the power motor. Well remove the nut and then the ring terminal. Then well go ahead and install the new ground cable that will run to our Superwinch coupler and secure it with the nut that we removed earlier. Next, to clean up our install look well take a few zip ties and just zip tie the cables together, then well cut off the excess from our zip ties. Now well move to the installation of the power wire from the rear wire up to the battery. Starting at the rear bumper well go ahead and install the connection cap. Then well take a long zip tie, run it through the coupler, around the hitch tube and then back through the coupler, securing our connector to the hitch. Then we can begin routing our wires. The positive wire, which will be the longer of the two, will run all the way up to the battery, and the negative wire will run up to the manufacturers frame. Well use some black zip ties to secure our wiring as we go. In this application well feed the wire through the frame and up to the battery. Note, you can make it easier to route your wire if you use a pull wire, such as a stiff piece of wire, or in this case, a piece of air tubing. Well pre-run it through the frame and then attach our power wire with some black electrical tape and pull it into position. The shorter of the two wires will be the negative, or ground. Well use a self-tapping screw to attach it directly to the frame. Quick tech tip, its best to clean off any excess dirt, dust, debris, rust or paint before making this ground connection. Now with our wire pulled through the frame well go ahead and route it up into the engine compartment. Next well secure it in the engine compartment and then route it over to the battery. Just before we route to the battery well coil up any excess wire. Note before making your connection with the positive battery terminal well need to install the breakers that come with the winch set up. Well take our breaker kit, install it directly onto the positive battery post and secure it. Then well take the power wire that we just ran and connect it to the other end of the breaker kit. Now with all our wires run and secured well go ahead and cut off the excess from our zip ties to clean up our install look. This will complete the installation of the Superwinch trailer and vehicle electric wiring kit, part number SW2008 in conjunction with the Deka battery side bolt extender, part number DW05416 on our 2004 GMC Sierra.
