Do the shielded ignition wires have to be run separately from any other wiring or can they be bundled with my wiring harness? I'm building a pusher type & my wire routing options are getting limited. My headphone jacks & ignition key are on one side of the fuselage & my battery cables & main wiring harness are on the other side separated by a few inches. The battery is located forward of the pilot up in the nosecone area. If I do run the wires parallel to some other wires is there a minimum number of inches that must be keep?

    you can bundle them.As long as you use shielded wire and properly ground the shield (18 gauge tefzel M27500-18TG1T14 is the most common wire used)
    The tach wire is very sensitive to EFI so it is a good idea to use shielded twisted pair wire and ground the tach in location away from the mags, radios, etc that produce interference. 22 gage twisted-pair: M27500-22TG2T14
