Anybody have a harness connector pinout diagram for a 16197427 PCM?

Here you go. ftp://ftp.diy-efi.org/pub/gmecm/manuals/16197427/ . HTH

MrBill

Sweet. Thanks!

Are you cooking somethng up for this PCM? If so, count me in. I have a lot of info on this PCM and have been messing with it for a while.

MrBill

No, not really. I'm building a Prominator for a 512K PCM and just need to set up this 7427 I have to test it with.

Sorry to disappoint. LOL

Hey HaulinA$$,

I've been searching for a component/board level schematic like the ones on ludis' page for the 16197427. Any Ideas on where to find one??

Sorry, didn't mean to hijack the link but ...... the ? is semi-related.

Thanks

Hey 89350STRO, I have not found any specific schematics for the '7427. It has some similarities to the 1227747 such as the injector driver circuits but that is as far as I got before giving up. From what I can tell, it is a hybrid of the P4 ECM (faster cpu and aldl, no onboard ROM, etc.) and the older C3 ECM (peak/hold injector drivers) with added transmission control. Sorry, that is the best I can do. If you ever come across schematics, let me know. HTH

What about pinouts for a 16196395? Same as the 6396?

try this website, lots of interesting stuff. look under wiring, and there should be numerous late model ecm stuff for trucks.

good luck!

MrBill

Need a pinout for a 16191947 now. Anybody?

They are the same as the 16197427. It is the same PCM. HTH

So i found this thread but im confused.

For the Jbody project i'm converting a ln2 pcm that runs in a s10 with the ln2 engine to run in a 95 cavalier with a manual trans and the ln2.

My question is, where can i find the pinout to the 16196285 and 16196395 pcms.

I have a sacrificial pcm to get female connectors and i have male connectors, and so what i need to know is where the pins plug. Im doing some google searching, so i will let you all know if i find what im looking for.

I still am benching the 16196285 pcm, but im finding the the 36 mask is uncommented and hard to figure out.

3 years later, any luck with that 16196395 schematic? 1/04/2010

Same as the 16197427 is the 16197395. Wiring diagrams are here:
