How do you install a tachometer in a 1986 Olds Cutlass Supreme?

Answer 1

Providing that you have a stock Vehicle ignition system, we just put a tach on our 90 350 and there are two plugs on the coil, a single wire comes from the fire wall, the other has two wires and comes from the dist, out of that plug there is a short wire pig tail that is just hanging there and it has a protected male terminal on the end of it , plug your applicable tach sensor into that connection and follow the tach install instructions to hook up your lighting and ignition wires. Most new tachs come with installation instructions. Happy Reving

Answer 2

To properly install a new tachometer in a 1994 Integra LS the unit must be correctly mounted. Part of the mounting process is correctly splicing the wiring into the old harness so the RPM can properly read the information.

Answer 3

Take off the cover on the steering wheel shaft Take off the center console around the stereo take off the pieces around the instrument cluster unbolt the cluster, unplug the connectors and take off the tach cable at the back. Take off clear plastic cover and unbolt the tach part of the cluster. Put new one in. DONE and DONE!

Answer 4

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.
