Clean 12v switched source that is hot cranking and running

I looked at that truck Dion and thought "Maybe" but it still shows a ballast resistor. So without that switch in hand, I don't know HERE IS THE THING Others have successfully installed EFI with no problem so I'm not sure I "see" this. It "might be" that if some switches in some cars are a bit "iffy" they might "glitch" sometimes between "S" and "run." But I think normally the answer is way simpler.

Also unless I mis-read that truck diagram it appears ther are TWO battery sources?? Looks like (I think) Red is b1 and Pink is b2?

Yes, both go back to a splice and are power feeds. I think they did it to cut down on the amps in the connection?

I agree it might be overkill to do this swap. But I also have seen several people on here recently saying they couldn't get their new Hemi swap to fire. Someplace I read that those are really picky in this regard and people have had to buy some kind of add on module. I don't think a Magnum swap would care as much unless you are really slow going from start to run, but I do think the G3 Hemi's have an issue with this. And so far it seems like the only solution I have seen is a push button for the starter and divorcing it from the switch entirely.

I could bring you one of these switches when I deliver that 400 if you wanted. :rofl:
