After 11+ years of going just by ear, and with diminished hearing, I decided to get this tach just to set the idle speed. Don't plan to mount it permanently. https://www.ebay.com/itm/2-in-1-Dig...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649
Instructions say Black wire : Ground wire, connect battery negtive output (DC - ) Red wire: Power supply, connect battery positive output (DC +) Yellow wire : Speed signal cable, connet to ignitor outlet or trigger lines
My limited knowledge of electronics is sufficient to know where the red and black wires go, but where would you electrical gurus suggest connecting the yellow wire? I've read threads on other tachs where they just wrapped a wire around the spark plug wires. Would this work?
