Al relays are wired up the same way. wires activate the coil that closes the relay points and once that is achieved then it is direct current to what ever you have hooked up. So the wires that come --power wire --from the switch ( what ever activates the relay) will be light wires and the other wires (from the battery to the compressor) will be heavy and of a gauge capable of carrying 80-90 amps continuously. Smaller wires will work but over a period of time say 5 minutes you will notice them getting hot and eventually the insulation will break down and you will have a short and/or fire

Go to faxonautoliterature. They have the original GM service manual for your truck which will have all the wiring diagrams you need, including all options. They also have separate manuals just for wiring. I've used them before and found service to be excellent. Hope this helps.

Few things that you must take care: you have to be sure about the purpose of the vehicle; Then you should consider what all options are needed for you purpose, like, is your engine strong enough to handle the load you are planning to take up; mileage should be considered very importantly; and lastly, if you find a truck that suits you before committing yourself do take it for a good check-up by a expert truck repair and service. These are few important ones one should take care of.
