Is it possible to keep old style electronic VR with a dual field alternator?
Either case it will get power when the key is in run ( and also when the key is in start). I don't know what the ECU draw is. Given a choice I'd go for 16 gage over the 18 awg for the wire to the votlage regulator.
For the ECU, it could be tapped in as a splice, or added neatly at the voltage regulator terminal.
