Or is this just the process of elimination because the other wires have resistance between those and the "right pin" and correct wire from the connector doesn't have resistance, but has resistance with another wire.. and then this wire needs to be connected to the green wire?? I'm confused thanks again..

Continuity = no resistance
I don't know what pin on the '99 harness is EGR temp, so I cannot tell you what pin to trace. I don't have a '99 service manual.
You need to find continuity (no resistance) between the EGR signal wire at the ECU and the EGR connector in the engine compartment. That line will hook to the green wire on your MAP sensor.
