Using Vehicle Battery To Power Trailer Tongue Jack.

Expert Reply:

Great question.

You technically could connect the Bulldog Powered-Drive Trailer Jack - Drop Leg - A-Frame - 21-3/4" Lift - 3,500 lbs - White # BD500188 to your vehicle lights, but we do not have the connector you would need to just plug into your tail light plug.

I have a solution for this though.

You can get the Lippert Power Stance Electric Trailer Jack w/ 7-Way Plug - A-Frame - 18" Lift - 3,500 lbs # LC89VR. This unit comes with a 7 way connection, allowing you to plug in and draw power from the vehicle.

If you do not have a 7 way connection you can add one with the Adapter 4-Pole to 7-Pole and 4-Pole # 37185.
