How to Wire the Lippert 421366 Replacement Tongue Jack for Use Without Lippert Ground Control System

Question:

Hello I just purchased a lc421366. I’m trying to use it just as a jack without the leveling system, would you be able to help me with a wiring diagram as the jack does not work using just the red power supply wire and ground.

You can use the Replacement Tongue Jack for Lippert Ground Control TT Leveling System # LC421366 as a jack and it sounds like you might be testing the function without it attached to the trailer, which is why it's not working. This unit does not have a ground wire since it grounds through the trailer frame, so you will need to install it on the trailer to achieve a ground connection.

From there, you will just connect the red wire with the fuse to your battery and it will operate normally. I confirmed this with my tech contact at Lippert to be sure and this would be the correct way to get your new jack up and running.
