PMag Firing Order Question

[Tankerpilot75]

As I understand it, PMags are a “wasted spark” ignition system with (Lycoming) cylinders 1&2 firing together then cylinders 3&4 firing together. Therefore (my question) does it truly not matter where the 1&2 plug wires are connected to the coil post and 3&4 are connected to the coil post as long as they’re connected to the appropriate side?

Page 8 of the manual says “1: It does not matter which cylinder is connected to which post within a given pair.”

This just seems strange to me.

The short answer is no, it does not matter if you swap #1 and #2 or #3 and #4.

Wasted spark

Dont feel bad. Still hurts my brain.
I'm an old car guy. Auto engines really run bad when the plug wjres are out of order.
