Thanks, I live on a small island so don't have a library but have a friend in another town who I think used to have alldata. I will get in touch with him.

The posted schematics are for a 1994 C2500 5.7 liter / 4L80E
The schematics do not show the PCM part number.

Thanks Dave. I looked them over and the pin out is the same as the 6395 and I have used 5.7 OE and 31 with my 6395 7.4 so even though the pcm number wasn't there I am pretty sure with the right bin loaded I could stick the 7427 in place of the 6395 and vice versa.

All four versions of the TPI PCM (red / blue connectors) are interchangeable.

I plugged my chip, zif, g1 and memcal from my 6395 into the 7427 and everything works the same so as long as the two are pinned for the same transmission they are interchangeable.

Ok so that means the iac is the same when swapping to a bbc throttle body with the flat four pin plur
