is it hard to install one if you do not have one? thanks

Yeah, you'll need the whole setup, from under the hood to the trunk. Do-able, but using aftermarket stuff will be easier.

Jason is right, as it'* a very complicated system. The compressor is meant to run ELC, with the utility inflator as an added option. There are control valves and relays involved, not to mention the ELC computer.

If you got the trunk trim, a relay, and the compressor, you could do the inflator by itself. From a wrecker, this would be over 100 bucks. That'* just for the compressor itself.

ok what would i need for an aftermarket set up..just the compressor i guess/// thanks

Well, it'* not in the trunk; the factory installation actually puts it under the hood (driver'* side, forward of the master cylinder), with some plumbing to carry air back to the rear suspension and to the accessory outlet port by the trunk latch. There'* also a wiring harness and relay involved for the control panel in the trunk, mounted in or near the trunk, and there'* some sort of timer or controller, maybe built into the relay like the defogger'*, which (according to the manual) will shut it down after 10 minutes of continuous running to prevent overheating the pump, although I've never run mine long enough to find out.

So if you're looking at a junqueyard donor to get the air pump out of, start under the hood and work your way back.

Here is an idea... buy a 30 dollar air compressor with a cig lighter adapter and put it in your trunk problem solved.

Ayup. I actually found an AC-Delco unit in a Jewel-Osco supermarket for $20. It _looks_ like it may be the same unit that'* under the hood of my car, stuck into a plastic housing.

any pictures of how you got it set up?

No, no, what I meant was that it looks like they may be selling the same pump over-the-counter as a plug-in accessory.

My own car is an SSEi that has it installed at the factory; I didn't mean to imply that I'd bought a pump at Jewel-Osco and retrofitted it into a Bonne that didn't have one; sorry. I haven't tried to do that.

I got one of those spare battery air compressor multi tool things for christmas one year that works well. Its small and fits in the side of the trunk without taking up too much room.
