It’s been a while, is there a separate power / engine controls relays ?
its just a relay that saves the ignition switch from a hard time.
i have got 12v on a skinny 1mm2 cable to my ignition switch. Same from the run position to energise a 70a relay and the same from the start position to the start inhibit relay.
my poor old Sierra ignition switch now only flows a few mA
I then have a heavy gauge wire from the master relay to a busbar setup.
