any one ever hooked up a tach on the above ? no dist looks like need extra pc not like old stuff used to asked sun pro same question also

 

You have a wasted spark so you need a converter of some type. not sure where, Maybe MSD? Also not sure if ur gauges are ran by a CAN bus, but if not you might be able to tie into the tach wire behind the gages. Or best thing is just get a cluster that has a tach in it. Those should be plug n play except the mileage part.
