A tachometer reads the engine revolutions per minute by the thousands in incriments. It works off of your timing sensor or if it is an earlier mdel car the rotary button in the dist. cap.
It should work. I have a 94 w/o a tach and put a LE version cluster with tach in. Works fine. There should still be a tach wire grouped into the harness plugs. Just unplug your old one and plug in the new one that's it.
It should work ok if the wire for the tach under the hood is connected and I don't remember which one it is.
Tach is driven by a motor signal, speedo is from the trans the sensor is bad on the transmission
Bad white wire
The tachometer is fed from the distributor coil. High voltage spikes are filtered on the wire to prevent damage to the electronic display. There is a tach filter attached to the intake manifold. Replace this filter and your tach will work again. Mid-America Motorworks Part #618-561
MSD had a module a few years back that would convert a tach signal. Not sure hear da rumor about using a wire off the obdii port, but never seen anyone with a mitsu do it and work. Have seen the MSD tach adapter work superbly.
Yes, however, the six cyl tach is different from the eight cyl tach. It will work but the RPM display is wrong.
bad ground or bad sensor or a short
For any of you who may have been watching this question, I'll give you the answer myself. The answer is YES. After purchasing the one with the factory tach and installing it, everything works like it should.
There should be a tach output connection on the side of the box somewhere, you just plug your tach pickup into that. If it doesn't work you'll need a MSD tach adapter. I'm unsure of the part numbers but there are 2 different ones, it depends on what you used to wire in your ignition. If you used the white wire there is one and if you used a magnetic pickup ( green and violet wires ) there is another one....MSD-8920. I have a sunpro tach and I had to go out and buy an adapter to make it work...for about 50 bucks.
It is similar to frequency . IT reds Time in close contac.
theirs a green wire by distributer that is for the tach
