tach help!
i will try to make this short and sweet...
i have a 96 240sx that has a broken tach, so i bought an external one to replace it. the tach i bought has a total of 5 wires: 2 power (red), 2 ground (black), and i tach signal wire (green).
i hooked the power and ground up right to power the tach, because when i iturn the ignition to accl the needle will move a litlle.
i hooked the power and ground to the gauge face up right, because when i turn my lights on the gauge turns blue.
but the signal wire was hooked up to the black wire that is traced with red that is in a harness on the side of the distributor cap.
so whats wrong? what do i do?
appreciate it
