ECM Fuse

[Iron Man]

I have a 07 Essex on a Spartan K2 chassis wth an Cummins ISM 500. Long story short for no apparent reason while dirving home the coach came to a stop with transmission warnigs and ABS warnings. Coach would turn over but would not start. I noticed the guages showed no battery voltage and no engine temperature. My wife began calling for a tow, while I mad a few phone calls. I thought it could be 1 of three things
1 a bad groung
2 a blown fuse
3 a bad ECM
I talked to a friend and he suggested I check the fuses, found the ECM fuse had blown. I replaced the fuse and drove 2 miles to the house and everything was fine..
My question is does anyone know the path of the power and ground wire for the ECM?
Also could more wires be involved in the fuse blowing other that the ECM power and ground?
