how does inhibitor switch work on 95 s14 automatic?

how does it know if car is in park/neutral etc . how does the switching occur? I assume it works like a computer? trying to diagnose a no start situation . the wiring diagram in fsm only shows the inhibitor switch and no relays at all.

just an idea, but you could do what the guys that auto-manny swap do and complete the circuit, so that the car always thinks that it's in park/neutral... find another connector from a junkyard or something, unplug yours and tuck it somewhere, and connect the two wires together from the donor connector to complete your circuit...

im not 100% sure that this would fix your s14's problem, since this is from my limited knowledge of my coupe that had the swap done... the guide that i read said to wire it to the neutral swith or something, and you'd still have to have the clutch depressed to start the car... on my car, my friend just connected the two wires together, so it car be started even in gear with no clutch... kinda dangerous for everyday use, but not a big deal if you're careful...

anyways, hopefully what i said makes since to you and is useful in diagnosing your problem... good luck!

There's a switch on the side of the transmission, it signals the ATC based on gear position. The starter signal wire is tied into the switch and only makes contact when in N or P. The switch is adjustable a bit, as in you can loosen the bolts securing it and rotate it to better align the gear selections, I've seen switches wear and begin to engage D in the 2 position and such, and the switch does wear out completely, I've replaced one before and sold a few as well. You can remove it and check continuity right at the base.
