M11 ignition start wire. Does it go thru the ecm first?

1995 FLD 112, M11 cummins. I have full 12 volts at the push button start switch both into and out of the switch. But I can not get any voltage to the activate pole on the mag relay. Does the wire leave the push button and go into the ecm before going to the mag relay?

 

Thanks for the quick reply. Is it common to have this wire beak somewhere?

 

I found the issue. Seems the previous owner or company, either had an anti theft device, or some sort of satellite controlled non start thing installed. Does a qualcomm have something like that? Anyway, I traced enough wires to find it and will remove it so all will be well again.
