Pin B is constant battery power coming into the FDCM that gets directed out to the lockers by the module. Pin B1 is ignition switch controlled power coming into the SmartBar to turn the FDCM on and off with each key cycle. Pin E and F are the grounds that are used for the module and lockers, they are a constant ground. What I don't know yet is whether Pin G and H are constant ground or switched on and off by the module.
The numbers in the middle of the wire paths indicate inline connectors somewhere in the harness and the corresponding pin number for that connector. The words to the side of the wires are the title of that particular inline harness connector.
I hope this helps!
