"ECM 1" is only hot in start/crank. Make sense?

Yeah I get that,I can't tell if the hot in run by ecm b is for that or the hot fuel module. If it's not then that would be 10a memory power

Keep Alive, Memory Power, B+ all mean it is fused battery positive.

Hot in run/crank is the ignition/injector power that is only hot with key in crank or run position. Not ACC or OFF.

See reply above with in quoted text IN ALL CAPS.
