Pmag harness

[gassman]

It seems that I read that the automotive style plug wire cannot touch each other because they are not shielded. If this is true what do I do with all the excess wire? I have pmags kit and right now I have it bundled behind the baffling. Obviously touching each other

They can cross each other. Here's the verbiage right out of their manual: "Leads should be kept separated. Do NOT bundle them together which can cause them to be inductively coupled. Wire looms can be purchased at auto parts stores, but a simple separator can be fabricated out of tie-wraps and ¼” segments of leftover MAP sensor hose."

My understanding is that the main problem with having spark plug wires close to each other is that there could be some inductive "cross-fire". The way the wires are routed and the firing order of the Lycoming 4-cylinder mean that if there is "cross-fire" it shouldn't cause any issues. Happy to be corrected!

I used these for the plug wires. Nice tight fit on the wires.

Modern plug wires are far less susceptible to this. My spiral wound auto wires on both planes have them tied in bundles. never had an issue. The good ones use silicone rubber jackets and they are good insulators.

Good to know. Thank you
