Wiring/Electrical Guru's, question for you.
I *ahem* accidentally removed my air temp sensor from my new wiring harness, and am reinstalling it, but am not sure which plug at the ECM the wire labled BR/B goes in?
I cant read this schematic too well, but it looks like several sensors are on the same wire, is it a ground?
I detailed what wires in my 2nd grade coloring project:

It is not a ground. It is a regulated 5v source for most of the sensors and does not come from the ecu. The closest connector is by the fuse/relay box by the battery.

So, uh, I spliced the green to the G, and the brown/black one to BR/B, reconnected battery, and now the PFC wont power up, at all. I pulled the BR/B out of the plug, and spliced it instead into the BR/B on the TPS plug (the BR/B has ~4 wires in it, then it goes to a blue plug and a yellow plug at ECM), hoping that it would help...no dice. Did I fry the PFC?

check you fuses, and make sure you have everything connected.
I can't find what 4D actually goes too...I traced BR/B all over the place and it terminates to the shielded wire on the ignitor/coils cable via X-05 which then turns to B/LG. But I never saw it go to the ECU.

Can you start the car with pfc installed?
If yes then you propably have burn a part o pfc if your car didnt start with pfc and start with mazda original ecu then you have burn the pfc.

I didnt try to start the car after I noticed that the PFC commander wasnt powered up. I figured there was a problem at that point, and decided not to risk any further damage.
As for using the stock ECU, I eliminated all of the turbo control/emissions etc... so if it did start, it wouldnt run correctly.
Is there a way to driectly test the PFC to see if its fried or not? I cant read japanese, and the www.apexi-usa.com manual is decidedly brief. Thanks!
