In my pre-made RB25DET-to-S14 conversion harness, Wiring Specialties provided a how-to for recalibrating the S14 tach. The ECU shows 900RPM and the tach reads 1100ish. Anyway, the instructions read, "...The adjustment screw will be in the back of the tach-no need to take the face of the gauges is needed..."

Aside from the freaky grammar, this seems straightforward, but before I pull the tach I thought I'd ask if anyone has a photo showing the location of the potentiometer trim screw? I'd rather know what I'm looking for before pulling the cluster back out. Mr. Google (web and images), and Zilvia/Nico search have revealed nothing of value.

Thanks in advance!
