EMS wiring cross-talk (Read 96 times)

What concerns are there about cross-talk between wires that would lead me to separate them from one another?  Is it safe to bundle, for example, a thermocouple lead and a magneto P-lead?  Two or more serial lines?  I assume that other than power connections, pretty much any wire in a SkyView system carries very little current, so there is little concern about heat dissipation from wire bundles.

No concerns, IMO. Thermocouple leads are very low current. Mag P-Leads are shielded with shielding grounded at one end to avoid EMI. I have all my EMS engine wires and Mag P-lead running through the same firewall hole with no issues.

That's what I hoped.  I already have a largish firewall penetration, per Van's (RV-6A) firewall-forward drawings, and I'd like to/plan to run mags, alternator, and all the EMS sensor leads through that one hole.

Thanks!
