Hey guys during crank I get under voltage from jbe diagnosed with ISTA. I figured out there’s a B+ wire leading from the jbe’s circuitboard to a separate relay. The relay then has another b+ wire going out of it into the car. Only the one that goes into the relay gets under voltage. It comes out from Z1*12B (first picture) then goes into the relay (attached in comment picture )

Please help

Hey guys I was doing some work on my 528xi. Had to replace the timing chain and guide. But to get to it I had to remove a lot of things and now I’m in the process of putting it back together. But I just can’t figure out where this one connector goes.

It’s the second connection on the ecm.

Thanks
