Today I wired up the two P-leads. First I carefully crimped the folded ends of two 130k resistors to ring terminals, then connected them to the signal wires for the EMS to EFIS. I heatshrinked these for strain relief and piggy backed them to the 18 AWG single-core shielded P-leads. I also added ground wires to the other switch poles and rotated the switches 180 degrees so that they're in the 'open' position when the magnetos are 'on'.
