ok so ive been going through all the escalade diagrams very carefully and i finally figured it out. you have to look closely at the connector label. they call it the pnp connector but its labled either C1 or C2. this is not to be confused with the connectors on the fuse block. c1 is the smaller 4 pin connector and c2 is the bigger 7 pin. so i made a revised pinout for the 03 harness in case anyone else such as dimebagged runs into this. i will also post this on his thread.
