I am elbows deep with switching the wiring over for the 411 PCM. I have 1 major question.
The LT1 Ign coil B+ is powered by a single 10A fuse. The injectors call for 7.5 A per side. The 411 calls for the IGN B+ to be tied into the Injector B+ and 15A per side. I have now problem with either option of split the leftover Ign B+ or tie it into the injector power. Do I just put in bigger fuses and choose one of those options, or do I run new wires? There is also the spare Ign hot to the LT1 PCM.

Injector solenoids dont pull much hence the low rating. Adding 4 coils to the same circuit bumps it up quite a bit. I bump them up to 15A for conversion harnesses. Some older F/Y body coils draw even more as they age. One car I wired needed 20A just to run
Thanks a bunch, Pocket. When I get a chance I'll trace it back and bump them up.
