The manufacturer of the tachometer should be able to tell you where to hook it up. Many late models require tapping into the "tach signal" input to the ECM.

If it's an Autometer tach, you can e-mail their tech support at service@autometer.com.
If it's another brand, go to their website for tech support info.

Thanx for the help, but you see, from the instructions that the company gave me, the wire that they told me to connect it to does not exist, the coloration that i found was different, and i tried connecting it to these other wires, but there was this one time that it went up but when went the opposite way when the air conditioner turned on, so i knew that wasnt the wire.

On mine, theres a wire on the Distributor Cap I tapped into that gave me the Tach Speed RPMs. And for the lights, i tapped into my Stereo Wire labeled "LIGHTS", don't forget your ground and power. I used my ACC Power to power up my tachometer. I'm running a Autometer 10,000 RPM with Shift Light Tachometer.

Negitive side of the distributor. It works, my 98 b14 this is what I did.

Get a wire tap connector and use it.

Mine was a Nordskog digital tach, however brand shouldn't matter.
