Question:

Is there a way to connect this Jack to the trailer battery or 7 pin connector on the trailer when my tow vehicle isnt close enough for the installed cord to reach? I want to retain the existing connection, but get some sort of alternate power connection from the TT Thank you

Expert Reply:

If you are wanting to draw power off of the battery on your travel trailer for your Buyers Products 12-Volt Electric Jack # 3370093500 then you need to install a vehicle-side 7-Way connector like the Hopkins # HM48480 on your trailer and run some wiring.

The wiring you need to run is for the power and ground functions. Simply run some 10 Gauge Wire # 10-2-1 from the power and ground pins on your 7-Way (see attached photo) and the connect the power wire to your positive battery post (with an in-line 40 Amp Circuit Breaker # 9510) and then the ground wire to your negative battery post. We have a wiring kit # 5506 which includes 25' of wire along with a few different size circuit breakers and a variety of connectors.
