  1. Hi, Does it matter which signal ground is used when wiring? i.e can you use either signal ground on any input, or do they have to be from the same plug? Cheers Greg
  2. Hi, I'm piggybacking to a factory ecu. Engine has 2 x two wire knock sensors. Can I just hook the G4 kncock sensor wires to the signal wire from the original knock sensors, and leave the ground wire attached to the original ecu, or does the G4 need to be referenced to this as well. Cheers Greg
