I have lotsa questions!

I am attempting to put a 1995 Silverado ECM in a 1979 C10. I know it isn't a thirdgen, but the subject matter is the same and I hopefuly will have a thirdgen in the near future. I just want the ECM to monitor the engine as it has a carb.

The ECM's service number is 1619742. I want to use the TTS Datamaster software with this ECM. I belive the ECM to be OBD I.

My questions are:

1. Where can I find a schematic for the Datamaster cable?
2. Where can I find a cable end for the ALDL port?
3. Does anyone have the cable ends for the ECM so I can make a custom harness?

Thanks!!!!!!!!!!
