Hey i have a autometer tachometer and i was wondering i have a 93 dx coupe. i have b16a2, and i dont have tach on my cluster. i went to autometer and got wireing diagram for my tach, and took it to my father in law, but he said you need to know where the tach lead goes to, on my car there is a white tab, looks like a wire goes in there its toward the back of the dizzy. I was sure the tach pluged right into the white tab on the back, but my fater-in-law said i have to be sure or you can short the entire moduleator out on this car and it can get very expensive can anyone advize where the tach would plug into under the motor, the green wire. keep in mind my car is obd1 with a harness conversion for obd2 injectors dizzy,intake mani.

is theres somewere i can get a wireing diagram, or someone can tell me where it goes? anyone? please.

 

See diagram for location of tachometer connector under the hood. The tach signal comes from a blue wire from the distributor.

 

At the dizzy, the two wire plug, use the smaller wire, which I think is blue. Don't mess with any of the wires in the other plug with 8 wires.

You can also use the blue wire going to the dash gauge cluster. Even on models like your DX that didn't come with a tach, the wire to the cluster is there and it is live.

 

i looked and all i found was that tach test underhood i was just going to use that for my tach, i wish i could find a diagram on the tach behind the cluster

 

If you download the honda service manual for your car by going to the link in RonJ's signature, you will find the wiring diagrams in the electrical section of the manual
