can i use a resistor or something on the signal wire to deemplify the signal or something in the tach (aftermarket) to make it work correctly since i have a 2.2 im sure it could be done and a tach adaptor would cost me 90$ a thing i dont wanna spend 90$ if it can b made for 15$ im handy i can make it if i have an idea on what to do!
not deemplify but to EMPLIFY the signal!
