I have a single mag and LSE. I'm running wiring through my firewall penetrations and I have some concern about the routing of the P-lead. I want to keep electrical noise out of engine monitor sensor wiring and the audio. I have a separate firewall penetration for the LSE RG-400 leads to the coils and I am planning on running the P-lead through the same opening. On the inside of the firewall I am not sure I should run the P-lead in the wire bundle routed to the instrument panel or keep it some distance away with a different routing. Any thoughts?
