Need help doing GM '870 -> GM '730 ECM SWAP!!!!!!

This is what I have:

GM '730 ECM with memcal & memcal prom adapter
MAP sensor
MAP knock sensor
Female wireharness header for '870 ecm (so can plug this to the stock male header)
3 wire harness for GM '870 ECM
Misc. Wire harness for MAP sensor

So I need some serious help from some guys/gals willing to help me do this conversion. I have the '870 ecm pinout description but it gets challenging looking at the '730 wiring and how to swap them together.

My goal is to repin the 3 '730 wire harness as necessary, wire them to the female '870 header, plug it up to the stock '870 male header in the car, misc wiring under the hood, install a prom and live happily ever after.

Easier said than done.

If anyone can point me to specific websites or provide detailed info i'll definetly appreciate it.

Brent,

You beat me to it! Excellent link (I've had it bookmarked for a while).

Here's another pretty good ECM reference:
