1227727/1227730 Connector Pinout questions - Third Generation F-Body Message Boards

-=Jeff=- · 06-28-2001, 11:15 AM

I have copies of the ECM pinouts for the F body and the Y body for these ECMs. What I really want to know if there is a crossreference for each and every pin betwen the two. The Y body has a few more sensors and I would guess the the 730 ECM will have the allowable functions but I cannot find info on which pins it will be..

Thanks

If you got to the DIY_EFI stire you should be able to get the wiring diagrams, and then just compare them.

There is at least one difference that I know of, the 727 has one more output since it has been used to control a wastegate.

Be advised if you already don't know the connectors are totally different between the two ecms

Grumpy,

Yeah I knew the connectors were different.. I found what I was looking for too... it was on Ludis' webpage
