Yes, it is very possible to install/fit a 7-way trailer connector on a 2004 Dodge Ram 1500. I first recommend looking under the vehicle for a square ten pin connector. This (if present) will be located behind the rear bumper near the spare tire and will match the end of the 7- and 4-Pole Trailer Connector Socket part # HM40975-11933 which is what I recommend using if this connector is present.

If you don't have the above square ten pin connector then you will need to start with a 4-way, the Curt T-Connector Vehicle Wiring Harness part # C55504 and then convert this to a 7-way, the Universal Installation Kit for Trailer Brake Controller part # ETBC7.

We went out and measured the #F2135823353 and the inside depth is 3-1/8 inches and the outer depth is 3-3/8 inches. The end of the threading is a little uneven considering the cut from the manufacturer so the depths may vary between each u-bolt.…

Answer 9

You will need to start with a 4-way (if you do not have one). For that you would want the #118617. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller…

We don't offer a European 7-way, but I can tell you how to wire one IF the trailer isn't equipped with LED lamps. On the Jeep, you'll take the turn signal and brake lamp inputs and run them through a vehicle to vehicle taillight converter…

You are correct, you should only be getting output when the brake is applied, or the override switch is activated. It sounds like the controller might be bad, but to make sure, you should probably bench test it before tossing it. Use a circuit…
