aftermarket tach wiring
can anyone tell me how to wire up my aftermarket tack on a sohc.. the tach has red black yellow and green wires.. im guessing the green is the rpm wire but have no idei what wire to splice into
ok i tried tapping into the grey wire with the blue strip and got nothing.. it worked a little hooking it up to the coil but not so hot.. any other hotspots that will work?
