Video Transcript for Demco Tow Bar Wiring DM9523069 Review

Speaker 1: Today we're going to take a look at the Demco 7-foot long 7-way to 4-way trailer connector adapter. Now, this adapter will run power from your motor home to the towed vehicle using the 7-way here and the 4-way round connector. It is a coiled cord so it stretches up to seven feet in length, prevents the wires from dragging on the ground and the cord will contract for storage. It is designed to withstand the elements. It is a vinyl-coated wire. They use silicone-injected plugs.

This part will include everything here on the table; the coiled cable, the two female connectors, the 7-way and the 4-way round and the one 4-way male connector plug and a nice set of detailed instructions. Extended length on this again is seven feet. But that should do it for the review on the Demco 7-foot long 7-way to 4-way trailer connector adapter.

Demco Trailer Connector Adapter - 7-Way to 4-Way - 7' Cord - DM9523069

Average Customer Rating:  4.8 out of 5 stars   (9 Customer Reviews)


This connector works as intended. The only improvement that I would suggest is that the blue wire sleeve to connectors be more secure. The coil in the line is so strong that over time the wire sleeve has pulled out of the smaller connector. I now have to figure out how to stretch it so that I can slide it back in place and more securely tighten it. I'm afraid that the wires themselves my eventually pull loose from the connector.


Got what I ordered, was very happy


As always, years of experience in dealing with etrailer another satisfaction notch thanks.



Works fine.

  • 4-Way Wiring Configuration for Demco Trailer Connector Adapter # DM9523069
    I am sorry for the confusion regarding the 4-Pole wiring on the Demco Trailer Connector Adapter # DM9523069. I went out to our warehouse to try and look through the manual that comes included and the 4-Pole wiring configuration was listed on the backside of the first (and only) page. On the socket end of the 4-Pole round connector the upper left pin is for yellow/left turn and brake, the upper right pin is for green/right turn and brake, the lower left pin is for white/ground, and the...

  • Tow Bar, Base Plates, Wiring and Braking System to Flat Tow 2012 Ford F150 4x4 Without EcoBoost
    To flat tow your vehicle, you will need a tow bar, base plates that install on the vehicle and provide a connection point, safety cables, a wiring solution and a supplemental braking system.
