Help wiring arb

Hey everyone I just recently got another taco after totaling my 99. My new one is an 87 and it came with an arb compressor and lockers installed by the previous owner, my problem is that the air compressor is not completely hooked up, I need to hook up a black, red, yellow, and green wire and not sure where to wire them if someone can please help that would be great I've been searching around all night, I'll post a few pictures

 

Looks like an older model. Is there a model # anywhere on the compressor? Are the switches wired?

 

Here's a picture of the part number

 

Red is for sure the hot for the compressor and the green and yellow are for the lockers and the black is ground, problem I'm having is, I don't know where to hook them up at in order to have my toggle switches on the dash actually be function able, I can hook them directly to the battery but that doesn't do me much good, any advice is much appretiated

 

Are the locker solinoids wired? All your needing to wire is the compressor?
The compressor needs a power lead from the dash switch in to the pressure switch then out of the pressure switch to a relay. The relay will need to be wired up to send power to the power wire on the compressor. The relay will need a ground as well as the compressor it self.

Really just google "ARB wiring schematic" and you'll get several good schematics. Its not that hard.
