Video Transcript for Hopkins Wiring - Trailer Connectors - HM37918 Review

Today we're going to be taking a look at the Hopkins Wiring Harness with the 5-Pole Flat Trailer End Connector. The 5-Way Flat Trailer End Connector is going to plug into the connector on your vehicle to power your trailer's signal lights. This does include the reverse function to release brakes when backing up, so it's ideal for use with marine type trailers equipped with surge brakes. Pretty simple installation, it just hard wires to the existing trailer wiring. It's going to feature corrosion-resistant terminals that are long-lasting. We have nice grips on the connector, so it has that easy grip design, which really helps when plugging this in and disconnecting.

This is going to work with most 4-way connectors. The harness length is going to measure 18 inches long. When it comes to the wire configuration, your white wire's going to be your ground. Yellow is left turn and brake. Green is right turn and brake.

Brown is for the tail lights, and blue is for your reverse lights. Now the 5-way design will also work with small utility trailers that have electric brakes. For this type of application the fifth wire, which will be the blue wire, will need to be wired to correspond with your end cab electric brake controller. That's going to do it for today's look look at the Hopkins Wiring Harness with the 5-Pole Flat Trailer End Connector.

Ask the Experts about this Hopkins Wiring

  • How To Attach Trailer with Six Way Using Vehicle with Four Way
    In order to reverse a trailer with surge brakes you most likely need a lockout feature. The most common type of lockout feature is electric which would seem to be what you have due to the type of trailer connector installed. I do have an option for you but the four pin trailer connector on the vehicle does not contain a reverse circuit which is needed for the electric lockout. I have attached a few options below. Option 1: The first option would be to remove the six way on the boat...

  • Replacement for Atwood 61101 Brake Actuator
    The Demco Hydraulic Trailer Brake Actuator part # 8605001 should be a direct replacement for the Atwood 61101 Brake Actuator that you have now. This is a bolt on option that mounts on 3" centers. The review you are referring to, the customer did indeed weld the brake actuator to his tongue but this is not required for installation because it is a bolt-on actuator. Unfortunately, we do no offer a bolt-on brake actuator for drum brakes with a manual lockout that will work for you therefore...

  • Can Trailer Back Up With Demco Hydraulic Trailer Brake Actuator # 8605001 Installed
    The Demco Hydraulic Trailer Brake Actuator # 8605001 that you purchased doesn't have an electric or manual lockout integrated so to back your trailer with the actuator as-is would mean you need free-backing brakes on your trailer. You still have the option to add an electric solenoid though with part # DM5837. This installs by threading it into your master cylinder and then allows you to back your trailer up when you connect the wiring to the reverse light circuit on your tow vehicle/trailer....

  • Will the Titan Brake Actuator T4749600 Allow for Reversing Uphill
    The Titan Brake Actuator part # T4749600 does not come with a lockout so in order to reverse you'll need to install a lockout solenoid, the Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts part # T4748800. This would also require a 5-way trailer connector so you'll also need the Curt Trailer Connector Adapter part # C57187 and Hopkins Wiring Harness part # HM37918. That said, in regards to uphill reversing you'll need to do so very slowly as left over fluid...

  • How To Convert a Euro 13-Pin to a US 5-Way Trailer Connector
    If the trailer has reverse lights then you will want to use the Modulite Protector 5-Way Flat part # 119177 instead of the Upgraded Tail Light Converter part # 119130 on your 2011 Volkswagen Jetta. Then in order to make an adapter that attaches the Euro 13-Pin connector on your trailer to the US 5-Way connector on your vehicle you will need the following: Hopkins Wiring Harness with 5-Pole part # HM37918 Curt 2-To-3-Wire Tail Light Converter part # C56196 Vehicle Side Euro 13-Pin Connector...

  • Correct Demco Hydraulic Trailer Brake Actuator For Use with Disc Brakes
    For starters, the Demco Hydraulic Trailer Brake Actuator part # 8605001 is for drum brakes only and it sounds like you have disc brakes. Therefore, the correct Demco Hydraulic Trailer Brake Actuator for use with disc brakes is part # DM8605101 which does come with a reverse lockout feature. In order to use this you will also need a new trailer connector, the Hopkins Wiring Harness part # HM37918 and an adapter, the Adapter 4-Pole to 5-Pole Trailer Wiring Adapter part # 47515.

  • How To Hook Up Trailer Lights on a Honda Goldwing Motorcycle
    It sounds like you may be trying to plug a motorcycle with separate tail light circuits into a trailer with combined tail light circuits or vice versa. If that is the case then you will need to use a separate to combined converter box. For example, if the motorcycle has separate tail light circuits and the trailer has combined tail light circuits then you will need part # RM-732 but if the motorcycle has combined tail light circuits and the trailer has separate tail light circuits then...

  • 7-Way to 6-Pole Trailer Connector Adapter for Horse Trailers
    Most horse trailers have a 6-pole trailer connector. In order to attach the 6-pole trailer connector to your vehicle then you will want to use the Hopkins Heavy-Duty, Coiled Trailer Connector Adapter part # HM47083 if the center pin on your vehicle connector is for 12v power or part # HM47085 if the center pin on your vehicle connector is for the brake circuit. You will need a 7-way connector on your vehicle in order to activate the trailer brakes on your horse trailer. If you do not...

    If your motorcycle trailer has a 5-way flat then you will need to use the Curt Trailer Connector Adapter part # C57187 in order to attach it to your tow vehicle. However, if your motorcycle trailer has a 5-way round then you will need to remove this and install a 5-way flat, the Hopkins Wiring Harness with 5-Pole Flat Trailer Connector part # HM37918 as there are no adapters to go from a 5-way round to a 4-way flat.
