  • Trailer Wiring Harness Recommendations for a 2007 Buick Rendezvous
    If you look behind the bumper below the driver side tail light and find a triangular plug that is not connected to anything on your 2007 Buick Rendezvous, then you can use the Hopkins Custom Fit Vehicle Wiring, # 41405.I have included a link to the installation details for reference. If the plug is not there, you will need to use Tow Ready Custom Fit Vehicle Wiring, # 118383. This harness connects behind each of the tail lights. I have included a link to the installation details for this...

  • Troubleshooting Tail and Brake Lights Not Working on Trailer Wiring
    First thing you should do at this point is test the 4-way of the wiring harness with a circuit tester part # PTW2993 for voltage on all of the right pins when the taillight signals are being applied. Just like in the video I attached. If the voltage checks out there but the trailer lights still don't function right then the problem is on the trailer wiring. That would mean that problem is either due to a ground issue or a short issue. Make sure that the trailer side connector are clean...

  • Will the Available Hitches for the 2005 Buick Rendezvous Fit on the 2 Wheel Drive Model
    All of the hitches we carry, Class II and Class III, for the 2005 Buick Rendezvous (see link) state that they will fit the 2 wheel drive and the all wheel drive models. The tongue weight varies only between the Class II and Class III models, with the Class II models showing 300 pounds tongue weight capacity and the Class III models showing 350 pounds tongue weight capacity. The hitch can be installed on your front wheel drive vehicle and will not affect the rear suspension as long as you...

  • Trailer Hitch and Wiring for a 2004 Buick Rendezvous to Carry a 300 Pound Electric Wheelchair
    The trailer hitches with the highest capacity for your 2004 Buick Rendezvous have 350 pounds of tongue weight capacity. Provided that the combined weight of the scooter and carrier are under 350 pounds the hitches can handle it. I recommend Draw-Tite hitch # 75430. this is a Class III hitch with a 2 inch receiver. Even though the hitch can handle 350 pounds of tongue weight you also have to consider what the vehicle can handle. Depending on how your vehicle is equipped (and how many passenger's...

  • Can the T-One Wiring Harness #118383 Be Used on a 2007 Buick Rendezvous With Towing Package
    You will still be able to use the T-One Vehicle Wiring Harness, # 118383, on your 2007 Buick Rendezvous even though your vehicle has the tow package installed. This harness connects inline with the vehicle tail lights and gets power for the trailer lighting directly from the the taillights. This harness works exactly the same as the tow package wiring once correctly installed, see instructions. The advantage to using the tow package wiring, # 41405, is that the trailer lighting power is...

  • Trailer Hitch Recommendation for 2003 Buick Rendezvous AWD
    For a Draw Tite trailer hitch that is confirmed to fit all models of the 2003 Buick Rendezvous including the AWD models we have the part # 75138. If you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop. It also includes a 1-7/8 inch ball, 2 inch ball, hitch pin with clip, and a storage bag. If the ball mount kit does not include a ball...

  • What Wiring Harness Fits a 2002 Buick Rendezvous and How does it Install
    We have a couple of solutions for a 2002 Buick Rendezvous. You could use the harness from Hopkins that you were looking at, part # 41405. I would first check your Rendezvous to make sure you have the proper connector. It should be behind the bumper below the driver side tail light. It should look like the connector pictured. I have included a link to the instructions below. This is a complete plug and play part. You could also use part # 118383 from Tow Ready. This harness connects to...

  • Recommended Class III Receiver Hitch and Accessories for 2007 Buick Rendezvous
    The Draw-Tite Class III Receiver you mentioned, part # 75430 would be an excellent choice. The hitch has a 3500 lb towing/ 350 lb tongue weight capacity. You will want to check with your owners manual for the actual towing capacity of the vehicle, and abide by whichever figure is lower. The receiver installs by bolting to the frame, as you can see by examining the instructions and the install video I will provide links to. To complete your towing set-up, you will need a wiring harness...

  • 2004 Buick Rendezvous Trailer Tow Wiring Harness Connector Location
    There are detailed instructions and photos in the manufacturer instructions, see link, that lead you to the location for the trailer wiring harness connections on the 2004 Buick Rendezvous. You will be routing the wires to the back of each tail light and plugging the connectors from the T-One Wiring Harness, item # 118383, inline with the factory connectors that plug into the vehicle tail lights.

  • 2001 Pontiac Aztec Gives Parking Light Out Error Message with Trailer Wiring Connected to Trailer
    If you are getting an error message that a light is out and no light is actually out, there could be a ground problem or a wiring problem on the trailer. Make sure that you ground the white wire of the harness to a clean bare metal surface. Check the trailer and vehicle side connectors for any corrosion and clean it out. Next, check that the grounds on the trailer are attached to clean and corrosion free metal surfaces. A lot of trailer tail lights ground through the mounting studs....

  • Adapting 6 Pole Square Trailer Connector on Tow Vehicle to 4-Pole Connector
    We offer an adapter that would allow the 6 pin on a Jayco to be towed by a 4-pole connector on the vehicle, part # A10-6034VP, but you're needing a connector that would work the OTHER way. We don't offer one, but I do have a solution or two for you. If the connector behind the rear bumper and below the driver's side taillight isn't being used, you can simply plug in the # 41405 to provide a 4-pole. If it is being used, you can use the # 118383 that would plug inline at the connection point...

  • Trailer Hitch and Wiring for a 2002 Pontiac Aztek
    Draw-Tite trailer hitch # 75430 is indeed a fit for your 2002 Pontiac Aztek. I have included a link to the instructions and at the top you will see the vehicle fits for this hitch. I also included an image of that part of the instructions. The video I have linked is on a Buick Rendezvous but the installation will be nearly identical on your Aztek. Since you mentioned that you are replacing a hitch you may already have towing accessories. But if needed I recommend etrailer ball mount kit...
