ALDL OBDII Connector Pinout
 

I am working on a 96 LT1 Engine swap and need some information as to how to wire the ALDL OBDII diagnostic port to the PCM.

For now I know the following:
There are six connections to be made:


pin 2
pin 4 Ground
pin 5 Ground
pin 6
pin 9
pin 16 Battery +

I need the ECM connector reference for pins No 2, 6 & 9
Any help greatly appreciated

FYI on my conversion, I have an OBD II port but the PCM is OBD I. I ended up only using the serial data port and ground to read and program. Not sure if OBD II PCMs will be the same.
