Question:

I have another question. If I get the prodigy rf. My second tow vehicle has a Hopkins 42205 wiring flat 4 pin connector. If I get the HM47180 multi tow adapter does just connecting it to the 4 pin sufficient to make the prodigy rf work?

Since you have a 7-Way you will only need a few more components to complete a brake controller install on your vehicle.

First let's start with a brake controller. I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to set up.

Next, for a wiring kit to install the brake controller to the 7-way you would want the Wiring Kit for 2 and 4 Brake Electric Brake Controllers # 5506. This will provide the power source and ground for the wiring for the brake controller. You will need to test the wires from the brake pedal switch of your vehicle to find a circuit that has voltage when the brakes are applied and none when not applied. This will be the circuit you will run the red wire to.

Finally you will need to run a length of 10 gauge wire (part # 10-1-1) from the brake output circuit of the controller to the brake output circuit of the 7-way (blue wire). The # 10-1-1 is sold by the foot so you will need to order a quantity of the amount of feet you will need.

I attached an FAQ on installing brake controllers for you to check out.

The Prodigy RF brake controller part # TK94FR connects to a 7-way and only needs the taillight circuits and the 12 volt power circuit to be active. That means that if you plug your 4-way into the # HM47180 you'd have to complete the 12 volt circuit but once that's done you'd be good. You'd need to run that circuit to the positive side of your battery with 10 gauge wire like part # 10-1-1 through a breaker like # 9510 and you'd be set.
