Hooked everything up, checked some things out.
However I cannot communicate with the PCM via my ALDL cable anymore.
Worked fine the other day w/ old 7747 ECM.
Checked F9 pin, was in the right spot.
If I ground A14 I get codes, but still no communication.
Is there something different between the two?
I did start it, and it runs, but obviously need to communicate with it.
Looks like I need a new ALDL cable
Bummer, I have a bunch I made looks like the baud difference is the kicker.
Looking around online found a schematic for one.
Looks like a visit to radioshack is in the near future.
