Sold a motor... is the swap difficult?

I know nothing of these cars so I'd like input from some of you smart guys. I just sold a 2.2L engine out of a '98 Cavalier RS. The guy who purchased it is swapping it into a '95 Cavalier... My question is, will the '98 motor work with the '95 wire harness and ECU. I think he said he would swap the '95 head back onto the '98 block to solve the wiring harness issue. Will it work?

The heads cannot be switched... 95-97 heads are different. Also the timing will be off due to the difference in duration of the cams. Also the transmissions will be different. If i was him, i would get the 4t40e out of that 98 and ditch the 3t40e, and just swap wires and ECM.

Damn, I feel sorry for that dude who bought the motor. He actually bought it from a friend of mine but the motor was from my sisters rolled Cavy. The wiring harness and ECM are still available but the tranny got screwed. The housing has pieces broken off and the pan has a hole in it. He got the motor for $300 and I guess the guy is screwed now. Guess he should have known better though, we didn't pressure him to buy it. It that a decent price for the motor, what would a wire harness and ECM go for?

Thanks
