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.

I plan exactly the same and at the research I found your topic.
So I´m interested in your results if already done it.

Have a nice day

Brent,

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

Here's another pretty good ECM reference:
