Re: Switched 12v
You can still use the IGNITION terminal, it will support more than just the HEI feed current levels. (On this, I am assuming the wire you need the current from, is much like an MSD operation wire, simply turns the Sniper system on and off? If so, no problem with using the IGNITION terminal, with the HEI).
When I run an HEI that I do, idle uses 3.5 amperes, red line, 1.3 to 1.5 amps total. Difference is tht at lower rpm's, there is more time in milliseconds for the coil to saturate, than at higher rpm levels, so, idle, more amperage use, red line, significantly less.
