Hi All,
I'm working on a 94 GT which I'm converting from Auto to Manual transmission. Right now I'm probing the pins at the ECM connector and I'm having issues identifying the pins that go to the VSS and the reverse or backup switch on the MT. I bought the Manual transmission harness but I believe I've got the wrong one. I think the harness I received is the one for the V6. I saw a diagram that shows pins 3 and 6 go to the VSS but with the MT harness connected to the connector at the firewall ONLY pin 3 go the VSS.
Can someone share which pins coming from the ECM go to the VSS and reverse or back up light switch
Can someone show me a picture of the firewall connector pinout distribution? I couldn't find any pictures in the web

For this conversion I have ECM part number F4ZF-12A650-JB but I haven't connected it yet until I sort those issues.

Thank you all

I knew we had one but could not for the life of me, remember where I saw it.

Of course, it was JRichker's post:


Scroll down until you see the diagram for 94/95
