xxx_P are redundant inputs to the Safety Pal circuitry. example FGS is input to front gateswitch and the same input labeled FGS_P is input for the redundant safety pal circuit. both inputs are together, and are fed from the front gate switch, basically one input going to 2 different parts of the circuit board, and they must agree. how do you know you are having an intermittent GS_P input? i believe you can look at the MLB input for FGS, and also look at the PAL Safety input, for FGS_P they should both be Hi when the doors are closed. my print shows RGS and FGS for front and rear gate switches. can't find a GS_P input
