Grey water tank shifted?

Thanks, I took some quick grip clamps in reverse, put a couple of 2x4’s to distribute the weight on the plastic tank and put pressure to it until I could get at the wiring harness. I taped up the individual wires and put it back together. Not the best situation I was concerned I was going to break the tank.
The refrigerator now works and I put it on a spare fuse since it was available. I checked the operation of the refer by disconnecting the wires and putting my battery charger directly to it. I am thinking that that may be a nice back up power source if I have 120 available.
