You will need to connect the tach to a ground and +12v source, the signal wire will have to be connected to the ground on the coil. Since the truck is fuel injected, you will likely have to find a way to wire it in with the connector on the coil. Kyrasis6 Mazdatruckin.com
pin 48 on the pcm connecter is tach signal connect to your green wire from tach
How do you replace a turn signal bulb in a 1998 cavalier
There is no such animal as a "tachometer sending unit." The tachometer circuit is spliced into the ignition circuit and reads the actual ignition signal used by the ignition module.
green wire on aftermarket tachs are the signal wire i belive
There really isn't one anymore. The instrument in the dash is just a stepper motor, which gets a signal from the PCM. You will need an adapter from a tach manufacturer to hook up any kind of aftermarket gauge.
White wire coming from the distributor.... remove a section of sleeve from wire and splice the signal wire from tachometer to it!
There are 3 (maybe4) wires on your tachometer. One +, one - and one gives the signal to the rpm. You must connect this third wire to the ECM (ECU) rpm outlet (White wire) or directly to the ignition coils negative wire (blue - yellow) If there is a fourth wire on the rpm, that is the backlight. Connect it to the dashboards backlight system. Good luck.
Yes, that is usually where the rpm signal comes from.
Usually. It can also pull the signal from a spark wire.
There is a short in the signal light circuit.
DISCLAIMER: I am not responsible for your actions You need an ECU diagram of your vehicle. Find the correct pin # and find the wire that attaches to it. Use a wire tap and run that wire as the signal wire to your new tach
