I put an 06 lq4 in a 88 suburban that was equipped with air conditioning from the Factory. I have the compressor from the new engine but how do Wire it up. I still have all the wiring that was original and it still hooked up to the controls under the dash. It has a two prong plug and so does the new compressor. The new compressor is not the kind that is always on, it has a clutch. Any help would be very appreciated.

Then I would wire it, as it was wired originally in the truck. Simply using the existing two-wire low pressure switch that is now on your accumalator/dryer. The two wires on the compressor are a black negative & a 12 volt positive green wire that comes from your existing A/C relay.
