That's a good idea, I'll just run the blue switched 12v directly to the VR and run one from there over the input side of the ballast, where it'll meet the supply for the ECU. That way I'll have two going into the ballast and two going into the VR instead of 3 and 1.

In case people were curious, after some searching, here are the gauges for the wires I'm replacing-

Yellow ignition trigger starter relay wire- 18 gauge

Brown start trigger wire for ignition ballast bypass- 14 gauge

Dark blue w/ tracer switched 12V for VR- 16 gauge

Dark blue switched 12V from VR to upstream side of ballast 16 or 18 gauge
