Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side interior trim panel in your rear cargo area.


Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your cargo area.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.


Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.


Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.


Curt SMT Circuit Boards

Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.


Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

Did not receive it with order



by:
2003 Pontiac Montana

The trailer hitch installed in about 20 minutes and has functioned well towing small trailers. The wiring took a little longer to interpret the instructions, but once we got started, the install was very simple. I did not rate the product 5 stars because I have not put a significant load on the hitch to know how good it might be.



by:
Oldsmobile Silhouette

Works great. Was difficult to find the vehicle in-line connector. It was hidden behind wiring and tubing for rear blower assembly. Once located, and pulled out to get to it, install was a cinch. But I did have to remove LR taillight assembly to get enough wire release to pull factory connector plug assembly out of it's hiding place. Obviously, it did not go back where it came from.

This van is the Premier version of the Olds Silhouette.

2004 Chevrolet Venture

Ordered this for my brothers 2004 Chevy Venture. Installation was simple: Plug and Play! It's been a year and it still works perfectly. Can't say enough about this company. Super fast shipping, and excellent tech support if you need it.

2001 Chevrolet Venture

Wow!. Fast service. I ordered this item on a Monday, maybe around noon. By the next day around 3:00PM it was at my doorstep via UPS Ground.
This item works exactly as it should and was a breeze to install. Just like the video on the etrailer website demonstrated, you just basically plug it in to an existing plug on the vehicle, (a 2001 Chevrolet Venture), and connect the white ground wire to the body of the vehicle. Thanks etrailer!

Did not work. Took the vehicle to the local trailer dealership where they replaced the unit with one of theirs. Been working fine ever since.

  • Troubleshooting Curt Wiring Harness Issue on 1997 Chevy Venture LS.
    If everything works at your 4-way when using the circuit tester like # PTW2993 for each function, before you connect your trailer, then the issue is most likely a ground connection on your trailer. You will want to make sure you have a bare metal to metal connection free of corrosion, rust, or debris. You may want to check your trailer lights as well as sometimes they have a separate ground connection. If there is not function on the 4-way on your vehicle, then I recommend you check...

  • 4 Pole Trailer Connector on a 2004 Chevy Venture
    I'm sorry you found the instructions with your wiring harness lacking. The 4-pole trailer connector is meant to be stowed in the rear cargo area when not in use. When you need to tow, run the 4 way out the door, and close the hatch on it. The weatherstripping provides enough cushion to prevent damage to the wires. Just be sure to keep the wire away from the latch, which WILL damage the wire. This arrangement protects the trailer connector from moisture, corrosion and damage. I use this...

  • Problems With Trailer Light Functions Using Curt Wiring Harness C55355 on 2001 Pontiac Montana
    Thank you for detailing your considerable efforts to troubleshoot the trailer lighting malfunctions you are experiencing with your 2001 Pontiac Montana equipped with Curt Tail Light Converter # C55355. Since you have tested the trailer with other vehicles and it has worked properly then the trailer would seem to have been eliminated as the source of the problem. Still, I suggest you check your trailer manual to confirm how much current is drawn by its lights. Curt T-Connector Harness #...

  • Location of Factory Connection Point for Trailer Wiring Harness on a 2003 Chevy Venture
    The plug will be there on a 2003. It is just that we have not had a 2003 Venture in to make a video but we have had a 2002 and 2004. To find the factory harness you will need to pull up the threshold panel in the cargo area so you can pull back the panel on the driver side. The wiring harness should be nearer the end of the vehicle. It can be either a single connector with nothing plugged into it or two connectors connected together. It can also be located behind an air conditioning unit...

  • Setting Up a 2004 Chevrolet Venture to Tow a 2,500 Pound Camper with Trailer Brakes
    Suspension supplements like the Timbren kits we carry may or may not be needed. At 2,500 pounds dry you should be within the tow capacity of the Venture. If your total trailer weight is close to the limit of the van, then I would suggest a suspension supplement. Since you will be towing a camper that will have pretty much the same load each time, I would suggest the Timbren Suspension Enhancement System as it will not need to be adjusted for varying loads. You would use part # TGMRREN if...

    On a 2000 Chevy Venture you will need to pull up the threshold panel in the cargo area so you can pull back the panel on the driver side. The wiring harness should be nearer the end of the vehicle. It can be either a single connector with nothing plugged into it or two connectors connected together. In either case it could be hiding behind another wire bundle or even taped up with another bundle so you cannot see it. I have included links to a couple of videos showing typical installations...

  • Trailer Wiring Harness Recommendation for a 2004 Pontiac Montana
    Actually, all you will need to do is install a wiring harness, # C55355, on your 2004 Pontiac Montana. But if you wanted to use those factory wires, because you have separate wires for turn signals and brake lights, you would first need to install a converter. The converter, # RM-732, takes the separate signals and combines them which is what a trailer uses. To wire it up your yellow wire will go to the yellow wire on the converter, green will go to green, white will go to white, and red...

    Since the trailer lights are working when connected to the 2008 Dodge Grand Caravan, it sounds as though the converter that is in your 2004 Chevy Venture trailer wiring harness might be damaged. You will need to use a circuit tester like part # PTW2993 and check the wire for the right turn signal that is going into the converter box. If it has power going into the box, then you will need to check the wire for the right turn signal coming out of the converter box. If there is no power...

  • Installation of a Brake Controller on a 2009 Pontiac Montana Van
    On a 2009 Pontiac Montana Van the problem is that the installation of a brake controller can shut down the brake light system in the van. The red brake wire that is on the back of the brake controller is normally connected to the cold side of the brake light switch to activate the trailer brakes when the brake pedal is applied. If that red wire from the brake controller is connected to the cold side of the brake light switch on the Montana Van it will shut down the whole brake light system. I...

  • Cant Find Connector Plug on my 2003 Chevrolet Venture to Install Trailer Wiring C55355
    Since the part # C55355 can fit a few different vehicles with differing setups you will need to check a few places to find the connector you need. First thing I would recommend is checking out the install video I attached to the right that shows this harness being installed on a 2003 Chevy Venture just like yours. Also, some vehicles will only have one connector. Some of the vehicle options have another connector plugged in series with the taillight connector plug, and the second plug...

  • 2000 Pontiac Montana With Insufficient Voltage for Turn Signal/Brake Lights at Trailer Connector
    It sounds like you have the ground taken care of. Are you using a tail light converter? Part # C55355 is the converter offered for your vehicle. The factory does provide the port for the towing wiring, but a converter is still needed. If you have a converter installed already, I would recommend testing the wires on the input side of the converter. You should have 12-volts entering and exiting the converter while each function is activated.

  • Difference Between Hopkins # HM41365 and Curt # C55355 Wiring Harness for 2003 Olds Slihouette
    Both the Hopkins # HM41365 and the Curt # C55355 would be correct for your Silhouette. Both wiring harnesses have the same capacity, preform the same function and would install in the same manner. I recommend going with the Curt option as we've found the converter in this particular harness to hold up better over time than other options like the Hopkins harness above. I included a link to the instructions for both harnesses for you to take a look at.

    This T-connector will plug into your vehicles wiring harness that is located in the rear cargo area of your van on the drivers-side. I have included a photo showing the location in the rear cargo area of a vehicle similar to yours. I would recommend using some dielectric grease # 11755 when you are installing this wiring harness, this can be used on all electrical connection points and it helps to prevent corrosion. After you have completed the installation of the wiring harness, the...

    Sounds like the wiring on your trailer might not be connected properly. You can use a circuit tester like the, # PTW2993, and test the wire connections on your trailer. The brown wire is for trailers taillights and should be connected to the vehicle's taillight. The white wire is the ground and you will want to check and make sure that it has a good, clean ground connection or if your trailer lights are grounded by the mounting studs that it is grounded properly.

  • Curt T-Connector Vehicle Wiring Harness on 1998 Oldsmobile Silhouette Shorting Out
    To run down a short in a wire you will need to use a circuit tester, item # PTW2993 if you need one, to test the wiring and find the short. The place I would start is on the vehicle side of the converter. Check each wire there, with a helper to turn on turn signals and step on the brakes and be sure that each circuit is functioning properly. While you are behind the taillights make sure the ground wire is attached to a good grounding point. Next I would test the wiring coming out of the...

  • Will Curt Class III Trailer Hitch Fit Short Wheelbase 2000 Pontiac Montana?
    Yes, the Curt Class III Trailer Hitch, # 13344, will fit your 2000 Pontiac Montana with a short wheelbase. This hitch would actually be my recommendation for you. I usually prefer Curt trailer hitches because I know they like to be a little liberal with their powder coating and in this case, it has the highest weight capacities of any hitch for your van so it has plenty of built-in safety margin. All of the wiring harnesses for your vehicle are basically the same thing, but built by different...

If there is any corrosion build up inside the connector, then that can cause a poor connection and cause the issue you are describing. If the vehicle side connector is cleaned out, you can go on to testing the converter itself. Start by testing the wiring going into the converter from the vehicle using a circuit tester like # PTW2993 if needed. If the wiring...
