Check first. Most likely, unless the previous owner removed it to sell with the crossfire, it's still in the car.

Thanks.
I don't really like the look of the rubber hoses and plan to replace with braided lines and AN fittings at some point. I tied into the original supply and return lines, I think the return is a 5/16", routed in front of the motor.

You sure the harness is all gone? Passenger side fire wall has a black box. Inside there should be 3 or 4 or more plugs. Most disconnect the wires that supply the engine compartment and crossfire there. From there those wires go into the cab of the car and back to the computer in the battery compartment.

Sorry, I should of been more specific on what I was looking for. I have all of the wires from the inside of the car to the firewall but I do not have the harness that connects the 4 plugs by the firewall to the crossfire unit on the engine.

Download a wiring diagram for that section of harness that you don't have, and make your own. It's not that hard so long as you can get the plugs.

I do have a picture that someone sent me of the harness and your right - it does not look like it would be too hard to make a harness. Where could I download the wiring diagram?

You could buy a shop manual, that would have a good diagram. Probably could use a TBI harness from most any period GM TBI car and adapt it to make it work. 87-95 truck/suburban, 87-92? Ciera, Century, Celebrity, etc. if you can't find an 82 harness.
