5.9 into '72 Scamp- search not helping...

Sorry for the hijack, but I just bought a low mile 5.9 Magnum from a 98 model 5 spd 3500. I got all of the underhood wiring, along with the PCM. I'm putting it in an 88 D100 automatic pickup, and want to keep the MPFI. Anybody got a wiring diagram of what I need to keep and delete in the wiring? Reading the above replies, will my PCM care what trans is behind the motor since it's for a stick truck? Will the magnetic pickup that is on my motor and for a straight drive, work with a flex plate?
