Default Double checking ECU wires for O2 clamp...

I really don't want to screw this up and I won't get much time to start and finish it. I plan on running a boost line to the ecu, I don't want to run a long O2 wire, I have had trouble in the past with this.

Is this correct for a 91?

The O2 wire at the ecu is Red with a Blue strip. (it is 2N, but connector 2 doesn't go up to the letter N!?)

The ground are the two wires on the very far right edge of the connector 2 facing the ecu.

The switching 12v wire is the far right bottom wire facing the ECU.

I am dumb, I already know, but rip on me if you want to anyways.

2N is correct, 2A and 2B are ground, and 1B is switched 12v positive
