You can purchase 2 types, one that plugs into the campground electric post and then you plug your plug into it, or you can get the hard wired one that is installed permanently in the motor home. I prefer the hard wired.
On my Tour Master it is installed under the bed next to the transfer switch. You will need a short piece of 50 amp shore cable to complete the connection. The vendor that sold me the unit gave me the cable. He is always at the Tampa RV show. He has a trailer that he operates from there in the show area. Be sure to mount the display unit where it will not be blinking in front of your eyes all night. I mounted mine low on the bed frame near the fuse panel, that way we can see it easily from the front of the coach. Hope this helps, you will get instructions anyway.
