Wow! I think I am using the wrong harness!!

Please correct me if I'm wrong, bc I have seen quite a few build threads and some have the grey and some have the yellow plugs.

I have a 90 7mgte and I am currently wiring the motor (on engine stand) to see if it is going to work.

I have a 89+ 7mgte m/t ecu. Both the harness and the ecu have the yellow plugs.

Am I using the correct one?

I also have a harness that has Grey plugs, can someone tell me the difference and why the one with Grey plugs does not go into my ecu.

Thanks
