hey i have a 93 civic ex and i recently put a new gauge cluster in and this 1 has a tach in it but the cars original one didnt have one so the tach isnt working because there isnt a wire, how do i wire the tach up??

 

You may have a bad cluster. I'm pretty sure that all models are wired for a tach even if they didn't have one originally. It would be a blue wire leading to the cluster.

 

ya the cluster should work no problem. ive swaped it before.

 

yea thats what i thought at first but then i put it in my other 94 civic which had an original tach and it worked perfectly fine.

 

maybe some one cut the tach wire before on the car... only thing i can think of.

 

Isn't there a sensor inside the distributor that gives the tach the signal? Perhaps the sensor in the distributor is bad?

 

well ive been looking around and askin ppl and im thinking that maybe i could run the wire from the cluster to the distributor and splice into 1 of the wires that would run the tach but the problem is idk the wire i need 2 splice into? so does ne1 think that would work?

 

On a stock '93, the tach wire is the small wire from the distributor plug with two wires. The tach signal comes out of the ICM on a pin dedicated for that purpose. Check that wire for continuity back to the cluster and shorts to ground.

If you have an engine swap, someone may have forgotten to hook up the tach wire in the harness.

 

alright thank you
