Two questions:
1) As I plan firewall passthroughs, how thick is the wire bundle for an EMS monitoring a 4-cylinder Lycoming?
2) The ignition is an SDS EFI / EI set up, with dual ECU's. I'm thinking the sensor wires should travel in a passthrough separate from ignition pulses. Yes or no? (Alternator and starter cables already routed.)

Plans built + moderate skills = a slow build. I'm lucky that it's fun. Thanks for your help.
