Hard to tell from my wiring diagram: Is the 12v keyed wire going from the fuse box to the printed circuit connector a resistance wire? Or does it become a resistance wire after the printed circuit connector?
AFAIK the resistance wires(yes there are two), feed directly to alt/regulator and coil... The alt excite circuit(light wiring) does junction with connection on cluster, but not a direct feed to it...
The 12v keyed power wire (red with blue tracer) that leads from the fuse box to the printed circuit connector is not a resistance wire then? It is simply a resistance wire coming from the printed circuit connector to the positive end of the coil... I'm just stealing keyed 12v for relays, so the alt regulator wire isn't a factor
