So here go's. Been a min since I've been on this forum sorry, had a wrench in my hand for the last year or so. At the end of my build.1991 S13 with an RB25DET GTS-T motor swap. Now using "wiring specialties" harnenss it says that for the S13 the " potentiometer " screw behind the tach in the cluster is my point of adjustment. Dose anyone know which way is which ? Clock wise is , what ? RPM up or down? Vise versa?

Why not pull it and find out yourself? Especially if you been wrenching for a year.

However, one would assume turning to the right increases rpm

LOL......so ur "assumption" isn't water tight. Unless u have something to back up ur " right is up in RPM" and " left is down ". I'm still learning my electronics sorry. I have an FSM on both the engine, to english, and the car. WS online site just explains where the point of adjustment is. So I'm trying minimize my, back and forth, if possible. If not then I'll do the foot work.

You could be figuring it out by turning a screw driver left or right with all that keyboard pecking and bitching. You're making this overly complicated. You know where you need to adjust, just turn the screw and find out which direction does what. THEN come back and provide your results.
