Thanks again

Well I can't show you as I no longer have the truck.... but I can explain it to you the best I can.

First off, have you ever wired a relay before? They are very simple to do, the relay itself actually shows you what wires to hook up where (in a way).

There's 4 (sometimes 5) prongs on a relay. Two of them are for your straight through power (from the main power source to the item you want to turn on) and 2 of them are for your switch. For my set up I ran power directly from the bolt on the TIPM, through a fuseable link, to the connector on the relay labelled "30". Then from the connector labelled "87" (directly opposite from your main power wire) I ran the wire to the compressor. Now the other two prongs left (85 and 86) are for the switch. One of them needs to be wired to a ground source. The other to a keyed source. To find a keyed source just get under your dash with a test light and see what's on keyed power. I believe I tapped into the control for my 4wd. It was the easiest one to get to and I knew what I would be tying in to. If you have 4wd just pull off the center bezel and test the wires that go to it... one of them will be keyed and I just spliced into it.

As far as mounting the relays go, I just built an aluminum bracket that bolted to the same spot where the battery tray bolts too and screwed the relays into it. That way it was a nice, clean install.

Hopefully that answers most of your questions. If you need anything else just let me know.
