Is Hopkins Tow Bar Extension Cord # HM47057 Wired with Center Pin as 12V Power  

Hey Walt, know the Roadmaster diode part #RM-690 does not have any over charge safety features. With that said most of the time the charge coming through this diode isn't going to be strong enough to really significantly over charge anything.

The gauge of the wiring in the Hopkins Tow Bar Extension cord part #HM47057 that you referenced is 14 gauge.

The diode #RM-690 can handle up to 120 volts at 24 amps so it should work just fine for your needs provided nothing else exceeds 120 volts at 24 amps. Regarding your picture, most battery chargers or batteries on vehicles say not to ground the…

I have a solution for you, but we do not have a pre-wired adapter to allow you to connect the 6-pin round plug from the tow bar to a 4-pin round plug on your Jeep. One solution is to replace the 4-pin round connector on your jeep with a 6-pin round…

If all you want is to prevent the 12 volt power supply of your trailer battery wiring from backfeeding onto your vehicle wiring or vice versa what you need is a one-way diode like part #RM-690. This only allows current to flow in one direction so…

The best charge line kit for flat towing your vehicle is the Roadmaster Battery Charge Line Kit #RM-156-25. I have a hard time not recommending all things Roadmaster when it comes to the wiring for a flat tow system because of how much research…

To see a couple diagrams that show how the 6-way to 7-way adapter part #47435 is wired up check out the pictures I attached. The 6-way of this adapter has the center pin as the 12 volt circuit. That is the usual circuit that gets moved around on…
