You'd have to get it programmed to your VIN, but there are some people who sell used PCM'*, and they can flash the VIN to it for you, then send it to you, from there it is pretty much plug and play.
I'm not sure it is the PCM though, is the mechanic using a scanner that can communicate with OBD 1.5?
