How to Maintain Electric Jack Ground Connection if Using the Jack-E-Up Quick Disconnect

Question:

I bought a 3500 lb electric a frame Jack from e trailer and it grounds through the trailer. I am going to buy a product called Jack e up which will allow me to disconnect and remove my Jack when hooked up. Do you know how I can get a harness that will allow me to quick disconnect and where do I hook up the ground. Thanks for your help.

So the question is are you wanting to use this device because your tailgate hits your jack or because you have bent the bottom of jacks in the past? Because if it is a tailgate issue there is a much simpler solution; a longer ball mount. But really the cost is about the same so 6 in 1, half a dozen in the other.

It appears that the device is made of steel so when your jack is in place it shouldn't lose the ground connection. You may need to scrape away any powder coat on the device though to get down to bare metal. If that doesn't work you could attach a ring terminal to the bottom of the jack mounting flange before running the bolt through. Then run a wire from that ring terminal to either the trailer frame or the negative battery terminal on the trailer.

It looks like that same company also makes a wiring kit for electric jacks so you can unplug it. If you do the ring terminal method mentioned above you could splice it into their harness but you would need another wire on the other end of that harness to go to the frame or negative battery terminal. The other solution would be to increase the amount of wiring on the jack's power wire by splicing in a few more feet (or however much you need).
