what wires on the back of yhe guage cluster do i hook a tach too. the car is a 96 dx

 

your tach signal wire.or you can go through the fire wall like i did, then find your coil box and look for the blue wire, splice into that and your good to go.

 

Signal wire is blue I beleive. That's behind the cluster btw.

 

yup yup the same wire.

 

Yea well I didn't know that.

 

Here's the wire I tapped into when I installed mine on my '92 CX (my '98 EX has the same wire so it's probably for all civic's). I didn't want to pull the gauge cluster and go hacking into the wiring back there so this was the easiest. It's a factory tach lead so you check rpm from the engine bay (for things like setting the idle and whatnot). I just lopped the plug off and attached the green tach wire (I think green, check your paper work) to this wire with a crimp connector.
