here's a few for referece:
no reference of the correct part numbers for various models/series in the FSM so i can only guess they are all N326 for the cars that actually used it.
for the most part i just disregard that it's in the car as they never seem to be problematic, i just recall that not all FCs used it for some reason.
it may be buried and still in the car somewhere in that mess they call the passenger kick panel, it is wedged in there kind of deep below the factory "knock box".
