...RPM tach mod completed...Used photo Pete Krok sent about modifying GRT EIS2000 for SDS system and verified by calling Sandy at GRT. It was as easy as she said. I used small needle nose pliers to pull the stripped thingie out and small dykes to clip the baloon thingie. Still no RPM so DD helped me and we discovered the EIS rpm pin was not installed in pin 5 so the handy RS extractor and a little patience and it worked like a charm.
