    When I installed my PF4, I repurposed the old HEI power wire and instead made it run a relay that pulls power straight off the battery (fused of course) for all the +12v ignition switched stuff in the engine bay. That way it also takes some load off of the ignition switch and the single wire going to the stock fuse box that provides power for basically everything but the headlights.
