This makes me look like a moron. I searched before I posted this. I may have even bought a new computer because I plugged the other one in wrong. There are 2 connectors with the same plug type. Which goes where?

All three plugs are different. Note the center black connector on the ECM, it has 24 pins versus the 32 pins of the other (outer) black connector.
The lime green connector plugs into the ECMs yellow connector.

Yep! That was my whole issue with no injector pulse on my other threads. I had the 2 outside plugs wrong. They both fit in the wrong spot. She fired right up! Thank you

That will do it. Although, the connectors have to have been modified as they are keyed differently between them. Can see the two ribs on the lime green connector in the photo. Then again I've seen ECMs where the connector housings are broken. This would allow the wrong connectors to be used.
