Thank you for this!
J10B-14RD coil + wire
J10D-14RD spark computer
J10C-14RD oil pressure switch
J10A-14RD alternator field coil
J10-14RD through the bulkhead connector to the ignition switch
looks to me that the coil +wire will be hot when the key is on or in the run position, but again, that can be verified with a multimeter.
