YO- have been searching and searching for an a31 chassis plug pinout, or someone who knows which wire is for tach.
ceffy was flooded past dash during a hurricane. having an electrical gremlin appear. tach is wonky reading consistent with a short, and on occasion the right side of my speedo lighting will flicker just for a second then go back to normal.
if no pinout available does anyone know if the tach harness opens or branches anywhere behind the dash? im suspecting a possible root behind the radio as there are more shorts in that area on the accessory loop.
