Using 2-Way Trailer Connectors to Go From External Battery to Trailer  

After feeding the wires through the Die-Cast Zinc Trailer Connector #337TC2012 and inserting them into the empty cavities, put the end of the connector back in place and secure it with the 2 side screws. Once this is done tighten the adjuster screw…

The Buyer's Products connector, part #337TC2002, does need the wires to be soldered in the brass fittings. Also, I verified with Buyer's that it's designed for 6 gauge wire so you may not be able to get your 10 gauge to work. You might be…

I think you may have your part numbers swapped around but the part numbers you mentioned all can work together. The 2-ways part #337TC1002 and #337TC2002 are perfectly compatible with each and the single pins #PK11851 and #PK11852.

The Pollack 2-Pole Connector, #PK12801, is designed to have the wires attached with ring terminals. By crimping on ring terminals to the ends of the wires and then holding them on with the included screw, it will provide a strong and quick attachment…

That would be a great idea. We don't carry 4 gauge wire, but the #PK12801 2-pole connector would work great for what you are trying to do. For the male connector you would want the part #PK12800. The connectors are rated for up to 200 amps so you…

You don't have to use an isolator if you don't need one. If your plan is to unplug the trailer when not in use there would be no need to use an isolator. For a 2 pole socket for your vehicle we have the part #PK12801 and then for the trailer…
