Where to run a certain wire off my tach?
I almost have my tach all ready to be re-installed after my new motor swap(B18C in my 92 Hatch). I had the wire off my tach that "reads" the "rpm signal" running to the blue wire off the distributor on my old motor, it worked but i think it was un-accurate. I heard you could run the tach wire straight into the ECU(P72 obd-1) but i need to know what wire/pinout to run it to? Please Help. THANKS!
