Read the tachometers owners manual to determine which of the tachometers wires is the signal wire and which is the ground wire. The wires are color-coded.

How can I increase the signal strength of my tachometer?

If you have a low voltage (4-5V) tachometer signal you can install a 680 ohm pull up resister from the 12V gauge power wire (ACC) to the signal wire to increase the signal strength. Connect one end of the resister to the 12V ACC wire and the other end of the resister to the signal input wire.

Where does the white wire from the tachometer connect to?

The white wire from the tachometer connects to the (—) negative post this supplies the ignition impulse to the tachometer. 12. With the engine compartment side (coil) connected the length of the dashboard side of the wiring harness was ready to cut to length.

Where does the Red Wire connect to the tach?

If tapping at engine harness connector, the RED wire connects to the upstream side of the wire (closer to fender), the R/LG wire connects to the downstream side (To engine/COPS) THe Gray wire goes from the tach adapter to the TACH (again, set to 8cyl).

What size wire do I need for a tachometer?

The wires are about 16-18 gauge usually, so get connectors of the appropriate size. Adjust the tachometer for the number of cylinders in your engine. New tachometers may be set to work on 4-, 6- or 8- cylinder engines by removing the back cap of the tachometer to reveal the cylinder setting switches inside.
