VEEDUBBED 0 Posted May 26, 2009 Right,i need to make a portable rev-counter to use on my 'raddo while tuning the mill. I've got a spare instrument cluster that i can break up and just use the rev-counter,there are 4 pins on the back of the small rev-counter head. I'd like to know how to wire up the pins?,which pin goes to the coil,earth,feed etc. Thanks for any info. Quote Share this post Link to post Share on other sites
