Hopkins 4 Pole to 6 Pole and 4 Pole Trailer Wiring Adapter Review

Today on this 2008 Chevrolet Express we are going to install part number 37175 from Hopkins. What this is is a 4-pole to 6-pole and 4-pole adapter. It will install on the existing 4-pole that is on the vehicle and convert it. The first thing we are going to do is tidy up the wires. We are just going to use some electric tape to secure everything together. While we are at it, we will go ahead and show you the functions of the wires. First off we will cover the function of the wires. This is the 4-pole itself and this will plug in to the 4-pole that is already existing on the vehicle. The white wire is the ground and that will get connected to the frame. And then we have the red and blue wires. Traditionally, blue is for brakes. However, on this particular 6-pole, the blue wire is ran to the center pin. So a lot of times the outside pin is going to be for brakes. It just depends on how your trailer is wired up. The red wire here is typically used for a hot lead. However, this is run to the outside pin. So you can actually use either one of these for the hot lead for 12 volts or brake lead, depending on how your trailer is wired up. On this install, we are actually not going to be using these. We are just going to use the 6-pole for lights only. 1:09

We are going to have to get behind the panels right here to get somewhere in this vicinity. It has got some special clips on the inside so be careful when you take them apart so they do not break because they will break kind of easy.

  • Wiring Harness Recommendation for 2003 Chevrolet Express Cargo Van
  • Yes, the Plug-N-Tow Vehicle Wiring Harness, # 31345, can be installed on your 2003 Chevrolet Express Cargo Van.

  • Brake Controller Installation on Forest River Motorhome on Chevy Express Chassis
  • The Chevy Express chassis most likely will not have any tow package wiring, but if it did there would be a bundle of wires under the driver's side floor mat up by the firewall. This wiring is more likely to be present if the motorhome has a factory 7-way trailer connector. You can contact Forest River Customer Service at 574-534-4058, and if you provide them with your VIN, they can verify if your vehicle is equipped with the tow package wiring. If the wiring is not present, you'll need...

  • Trailer Wiring Recommendation for a 2013 Chevy Express Van
  • What I would recommend you get is a Curt Custom Fit Vehicle Wiring # 55540. This wiring kit plugs inline with the tail lights of your vehicle and will activate the trailer lights of your small trailer. Curt has determined that you do not necessarily need a powered unit like the Hopkins Converters # 46255 or # 46365 and since your trailer only has two lights on it I think the # 55540 would work well for you. The main difference between the # 46255 and the # 46365 is that the # 46365...

If the wiring harness functions normally with no trailer connected, then there is a problem...

  • Installed Hopkins Custom Fit Vehicle Wiring Harness, # 31345, On 2005 Chevy Express, No Brake Lights

  • The Hopkins Custom Fit Vehicle Wiring, # 31345, that you reference is the correct custom wiring for your 2006 Chevy Express Van.
