Hey guys, was reading the "TBI Guys: Time to update!" thread and decided to get myself a 16168625 ECM...I've already torn apart the memcal and soldered in a ZIF for my Ostrich, however I now need to make an adapter between the 8625 ECM and the harness I have for the 7747 ECM & TBI setup in my truck. I already have a dead 1227747 ECM and the pigtails for the 8625, so I'm planning on soldering together a harness that adapts the 8625 into a 7747 connector (in the event I ever want to swap back to a 7747).

I don't need a pin-pin comparison as I can figure that out on my own and I got a 7747 ECM pinout from chevythunder.com...but I really need the 8625 pinout. Thanks!

 

Oh btw if you can't attach it here...send it to kris (at) speedyoldtruck (dot) com, thanks.

 

Double check the 'time to upgrade' thread. I am certain that there is a to-from list posted. As an image file.

I assume you are referring to 89350STRO's post, and thats a pin-pin comparison of the 1227747 and 16197425....not the 16168625 and 1227747, as per my original post I already have a 1227747 pinout from chevythunder.com

 

Ahh, Dominic threw a curve ball, but the bat finally connected. Check this thread:

I just posted 7 pinout/schematic drawings in the 'time to upgrade' post..
Enjoy!
