Tachometer wire testing
I think I may have a defective RPM switch...is there any way to test the tach wire to make sure it has signal? I tapped the wire going to the tach from the ecu on my b13(blue/black stripe) and its not working...the tach is working but not the rpm window switch.
I was hoping theres a way to actually verify the signal somehow
