Installation of the Hopkins Endurance Fifth Wheel Wiring Harness


Today on our 2008 Chevrolet Silverado we'll be installing the Hopkins Endurance Fifth Wheel Goose Neck 90 degree wiring harness with seven-pole plug, part number 41157. To begin our install we'll first go ahead and find the mounting location for our new seven-pole connector in the pickup bed. Now we've located it we'll go ahead and draw out a pilot hole.Then using our hole saw we'll go ahead and open it up to the final size as per the instructions. Now with our hole in the bed created well go ahead and get underneath the vehicle, take the wiring harness and feed it up through the hole we just cut out. Next we'll get back into the pickup bed, take our seven-pole plug and connect it to the wiring harness.Quick tech tip: before you make this connection I recommend you use the dielectric grease provided with the install kit to put it over the terminal connections. This will help to assist in keeping out moisture and corrosion.

Now we're ready to go ahead and mount the seven-pole in the side of the pickup bed. Use the self-tapping screws provided with our install kit.With that done we'll move back underneath the vehicle and go ahead and start routing our wire. Keep in mind when routing your wire to stay away from the moving components such as standard suspension or excessive heat such as exhaust. Now we've routed behind the bumper we can go ahead and remove the manufacturer's seven-pole wiring harness from the back of the seven-pole plug mounted in the bumper.Next go ahead and take the manufacturer's seven-pole connector and our new wiring harness, apply some more terminal grease to both connection points. Once we do that we can then take the seven-pole plug and the manufacturer's wiring and plug them together.

Then we'll take our new wiring harness and plug into the back of the seven-pole connector behind the bumper.Next we'll take the white wire with the pre-attached ring terminal to be the ground for our new seven-pole connector and secure it to the frame. To do this we're going to use a self-tapping screw. Now with our ground wire secured we'll go ahead and wrap up and secure the remaining portion of our wire. Once we do that we'll go ahead and cut off the excess from the zip ties to clean up our install look.This will complete our install of the Hopkins Endurance Fifth Wheel Goose Neck wiring harness, part number 41157 on our 2008 Chevy Silverado.

Trailer Wiring Harness Installation - 2003 Chevrolet Silverado

Today, on our 2003 Chevrolet Silverado, we'll be installing the Curt Custom Fit Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, part number C55515. Well firstly, we locate the manufacturer's round seven-wire connector. Note, if your vehicle is equipped to the spare tire, you may need to lower the spare tire to gain access to the wiring. To this application, we don't have a spare tire in the way so we'll go ahead and locate the wiring. Here on the cross member of the frame rail, let me just pull it down as it's clipped to the wiring harness. We now have access to it. We'll then go ahead, press on the locking tab or we can remove the cap. Once we removed the cap, we're ready to install the new 4-pole trailer connector.



Hopkins Endurance Fifth Wheel Wiring Harness Installation - 2004 Chevrolet Silverado

Today on our 2004 Chevrolet Silverado 3500, we'll be installing the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness, Part Number 41157. Now, to begin our install, we're going to our 7-pole, supplied with the install kit, and mount it here in the pickup bed on the driver's side, behind the wheel well, in front of the tailgate. This will give us easy access. To mount it in the pickup bed side, we're going to go ahead and drill through the bed liner, through the sheet metal, and then mount it using the self-tapping screws provided with the install kit. Now, we need to make a hole large enough for the back of the 7-pole socket, so we're going to drill out a 2-1/8 inch hole as per the instructions. Now with the hole drilled out, we need to take the 7-pole connector that matches the back of our 7-pole socket, and feed it from underneath, up and out through our cut out hole. Then, we'll go ahead and take the 7-pole connector, attach the wiring harness, and mount it to the pickup bed side. Now, I'm going to go ahead and feed the 7-pole over the frame and then up through our hole.



Trailer Connector Socket Installation - 2005 Chevrolet Silverado

Today, on this 2005 Chevrolet Silverado Extended Cab, we're going to install Part Number HM40975. This is the Pollak 7- and 4-Pole Trailer Connector with Mounting Bracket. Typically, this part can be used as a replacement on your vehicle. However, in this case, even the original is completely missing, but we do need this original OEM socket to make it work. If you have this on your vehicle, you should be good to go. Now it's a good idea to make sure that you have this completely cleaned out, as best as you can. Let's go ahead and just set this aside for now, and we'll go ahead and mount our bracket for our 7-pole connector. Mounting your bracket is a matter of personal preference. I like using this location right here for our two holes will line up this part of the steel in the bumper.





Fifth Wheel Wiring Harness Installation - 2010 Chevrolet Silverado

Today in this 2010 Chevrolet Silverado Extended Cab 2500 HD, we're going to install part number 54701-003. This is a 5th Wheel and Gooseneck 90 degree wiring harness with 7-pole plug connector. This our 7-pole connector, and this is the part that's going to get installed above truck. Now typical 5th Wheel application will be mounted towards the back via a sliding camper, chances are this may be installed forward of the truck. For this case, we're going to install our about this location right here. Once we have our location determined, we'll go ahead and drill a quarter inch hole. We'll follow that up with a 2-inch hole saw. We'll go ahead and clamp the mess we have right now and we'll also touch up the inside edge with something to protect the metal. Now we'll go ahead and take the end of our wire harness and I'll plug into a 7-pole connector in the bumper, let's go ahead and push it through and down. Make sure it's sitting the way you want it. We'll go ahead and use the included fasteners and attach it to the bed. We'll go ahead and take the self-tapping hardware and with a 5/16 nut driver, we'll go ahead and run it into the sheet metal of the bed. We're already done inside the bed, let's go underneath the truck and make our connection down there. All right to make things easier, we got our spare tire out of the way. Here's our 7-pole connector that goes into the bumper. There's a lock on this side here that will push down the tab and pulled apart. Sometimes there's a a little gray connector that fits inside here. This truck didn't have it, but if it did, you take a small screwdriver and you just back it out, out of the way, and it'd be just fine. OK. Let's leave that alone from now.
