Help!!.. Need Connector pin-out for a GM 730 ECM

Hi y'all,

I'm trying to change the pinout of my '87 Camaro's wiring harness connector
to accept the Haltec EA6GM computer.

Little background... while my car started life as a 2.8L V6, it is
currently configured as a '87 350 VIN "8" with a 165 GM computer and MAF
sensor.

Now Haltech supplied a wiring diagram for just the harness connector pins
it uses.  So far so good.  The system is speed-density using a MAP sensor. 
However, there are a lot of circuits missing from the Haltech pinout for
functions the box doesn't support (like the AIR diverter solenoids, EGR,
VATS, and ESK modules.)

So, what I'm looking for is the correct pinout of the harness connector for
a GM 1227730 Speed Density computer so I can fill in the missing blanks.

I know they will not function with the Haltech, but I'd like them wired
right from the start so I can plug a 730 ECM in when I'm done playing
around with the Haltech.

TIA,
