If you are using an internally grounded electric jack like the Ultra-Fab Electric A-Frame Jack, part # UF38-944017, you simply run the power lead to the accessory battery on the trailer and connect it to the positive terminal using something like a ring terminal, like part # DW05705-1.

You will also want to make sure the negative post of the battery is grounded to the trailer frame so the circuit is complete. This type of jack will only require the power lead wire to be connected as it is grounded when the jack is bolted to the trailer frame.

To make it more difficult for a thief to take my trailer when parked, Id like to hook up a switch to turn off the power to the jack when not in use . What type of switch should I use? Thanks

Something like the Epicord Battery Disconnect # 277-000096 (linked below) would work really well for this. It will install in line with the battery and actually uses a key to turn on/off power coming from it. The key is tethered to the switch, so for security purposes you might just want to cut it off so you can keep it with you while the trailer is parked.
