The blue wire is usually just an auxiliary wire. The blue wire does not need to be connected. Tape the end of the blue wire off.
A wire connects to a bulb by attaching one end of the wire to the metal base of the bulb and the other end to the metal contact on the bulb socket. When the circuit is complete, electricity flows through the wire and powers the bulb, causing it to light up.
The tachometer wire on an ECU is typically purple in color.
To hook up an aftermarket tachometer to a 1994 Cavalier 2.2, you can connect the green wire from the tachometer to the negative side of the ignition coil. This will allow the tachometer to receive the signal it needs to accurately display engine RPMs. Be sure to consult your tachometer's manual for specific instructions on wiring.
To wire two bulbs to one switch, connect the live wire from the switch to the live terminal of the first bulb. Then connect a wire from the live terminal of the first bulb to the live terminal of the second bulb. Finally, connect the neutral wire from the switch to the neutral terminals of both bulbs. This setup will allow the switch to control both bulbs simultaneously.
Purchase a tach and it will come with instructions for installation. There is a product called "Tiny Tach" used for ultralight airplanes. Very accurate digital, does not care how many cylinders you have. Installed by wrapping a wire around a spark plug wire, and connecting the other wire to ground. No tools. Self contained battery lasts 5 years or more. Available from Aircraft Spruce for about $39.
the green is the signal wire and it goes to the negative side of the ignition coil

connect the light bulb to the positive wire like a inline fuse and then connect the wire to the battery it should just burn out the bulb
On the 88 jeep the trigger wire at the tach is blue.
To install a tachometer in a 1975 Toyota Corolla KE30, first, locate the ignition coil and identify the negative terminal. Connect the tachometer's signal wire to this terminal for accurate RPM readings. Then, connect the power wire to a suitable 12V source, such as the fuse box, and ground the tachometer to the chassis. Finally, mount the tachometer securely in the dashboard and test it by starting the engine.
on my tach, the green wire connects to the neg on the ign coil pack
To install a tachometer on a snowmobile, first locate the ignition coil or the pulse wire, usually found near the engine. Connect the tachometer's signal wire to the pulse wire or the ignition coil's terminal, following the manufacturer's instructions. Then, mount the tachometer securely on the dashboard or handlebar, and finally, connect the power and ground wires to the battery or a suitable power source. Ensure all connections are secure and test the tachometer for proper functionality before use.
Blue wire is for a tach I believe
Connect the trigger wire to the yellow/blue wire that is joined to the Blue wire from the coil. Don't use the yellow blue at the coil, the connection you want is a junction point where the blue meets the yellow blue. It is at the plug that hooks to the coil. Just connected mine and it works fine - 2.6L 4 cyl. Connect the trigger wire to the at the Blue wire from the coil. Just connected mine and it works fine - 2.6L 4 cyl.
Connect the green wire to the negative side of the coil.
To install a tachometer in a Chevette, start by selecting a suitable mounting location on the dashboard or steering column. Connect the tachometer's power wire to a switched ignition source, and the ground wire to a suitable grounding point. Then, attach the signal wire to the negative side of the ignition coil or the appropriate wiring harness. Finally, secure everything, ensuring that the tachometer is calibrated correctly for accurate readings.
