This 7 pin trailer connector wire is very easy to work with and splices nicely. Used in conjunction with a terminal box and a molded cable this made my rewire a breeze. Spend a few extra dollars and buy heat shrink or heat shrink connectors and quality cable clamps 644613

Looks like a good solid cable but not installed yet. I like the finish of the connector pins and housing, they look serious. I don't expect any surprises but will amend this review if needed. 435450

Ask the Experts about this Hopkins Wiring

  • Can 12V Auxiliary Wire on Trailer 7-Way Be Used To Power Trailer Brakes
    The auxiliary or back-up wire on a 7-way trailer connector like # HM20041, is used to power to things like interior trailer lights or other 12V accessories. It can also be used to power backup lights, but not many trailers are equipped with those. There is a dedicated brake wire (typically blue) on your 7-way trailer connector which runs back to each of your brakes. This is the wire you want to connect to the corresponding brake wire on your vehicle's 7-way or 7 and 4 way like # 37185....

  • Comparing Hopkins 8 Foot Long Trailer Side 7-Way Connectors
    They are basically the same. Harness # HM20041 looks to be replacing H20046. The manufacturer no longer has a listing for the 20046 harness. Everything else is the same as far as length, wire gauge, and design.

  • Recommended Trailer Side 8 Foot Long 7-Way Harness with SAE Listing
    I reached out to my contact at Mighty Cord and she stated that they don't have any particular safety listings for their 8 Foot 7-Way # A10-7W8.
