Hi Mark, I guess I'm still not getting this. Please remember that I'm dealing with a 1.9L version here. The sender has one wire connected to it, blu/blk, according to the wiring diagram on 97.56. What do that sender do? My first guess: Pressure too low = switch closes, connecting the blu/blk wire to ground, Pressure okay = switch open, blu/blk wire not connected to ground, Pressure high = switch closes again, blu/blk wire connecting to ground again? Thanks for your patience, -- Rocky J Squirrel
