Does anyone know how I would hook up this wire from my Sandon compressor? Im converting to on board air and this connection came with the compressor from the junk yard. Theres two wires coming from the base (hot and a ground) but it turns into one wire after the stock connector in the middle.
Any help would be great.

 

the wire that come out of the plg is hot or ground after it plgs into the connector and where is the connection go on comp

 

So is the white single wire that comes out of the plug a power wire that I can run to the pressure switch?

 

dont no im asking is that wire hot or ground when the switch that will operate the comp is on and where are the conn on pump

 

I don't know what that wire is. At the very base of the compressor, there are two wires coming out. One goes inside the compressor casing and the other wire is screwed in to the side of the compressor casing.(ground?) They both run in the same wire loom to a connector plug. There's a connector that plugs into it but there's only one wire coming from it now. It originally ran to a bunch of other wires that ran to the HVAC controls in the donor XJ I pulled it from. Should I ditch the plug harness and run wires from both the ground and power?

 

i would and switch the power one with fuse

 

So I split them up and added some slip connectors. Also put some heat shrink around both wires casue they were pretty worn.
I'll probably add a wire loom and some cold shrink to protect it from the block.
Should I really put an in line fuse on the power wire? It will be running to the pressure switch and then to a relay. If it adds more protection, I'll do it.
I'm also taking pics of everything Im doing and plan on doing a write up of a simple reliable OBA set up. If anyone cares...
