first of all what kind of motor do you have? Either way your going to need a tack driver to boost the ground signal off of your electronic ingnition box to the remote starter. I've done this myself and it took a long time to figure it out but that's the only way I know 1998 Chevy Cavalier- Your tach wire is WHITE, at your PCM (Powertrain Control Module). 2.4L is white at PCM, and also the 2.2L is white at the PCM.
You should be able to use the power side of Injector #1 for the tach signal
Check for a loose "Tach" wire
i like to know what wire it is if any one knows email it to me firstname.lastname@example.org thanks
Your tach wire color is Gray. And it's located at Coil on passenger side of the engine. This goes for 1997 through 2001.
There should be installing instructions with the tach. If not contact the manufacturer.
In the wiring harness behind the parking brake. You will have to remove the plastic shield and dig around in the wires for it. Pink with White or white with pink. Can't remember. Consult your remote starter manual.
The instructions will come with the new tach.
The instructions should come with the tach. If there are none, get in touch with the manufacturer. no tachometer will work straight out of the box with a cavalier of that year, you must buy an adapter. it will only show half RPM
Your Tach Signal wire is Gray and Dark Blue (Gray/Dark Blue). Same wire, marked with both colors. This means the wire is GRAY with a dark blue line through it. It is located at the Coil pack on top of valve cover. --- This wire above is a 2 Cylinder Signal. 3.0L Tach Wire is GRAY/RED at Powertrain Control Module (PCM). 3.3L & 3.8L Tach Wire is GRAY/RED, DARK BLUE/TAN And RED/YELLOW at PCM. (Each wire is a 2 cylinder signal.)
Remote starters can use the AC signal from the alternator as an alternate signal which is not produced until the engine is running. On most cars if you access the PROPER wire for the tach it almost always is strong enough. Double check your wiring diagrams and make sure you are accessing the correct wire from the coil pak or ignition coils.
Connect the green wire to the brown striped black wire.
