The tach died on my 92 prelude, the ecu burnt two weeks ago due to some wire touching the battery and another piece of metal by the engine bay, so I replaced the ecu and some fuses but the needle for the rpm's won't move at all, everything else is fine, anyone knows where the tach is wired to?

 

there is a blue wire coming from the igniter in the dizzy, that goes inside to the tach.

mine got disconnected and everything ran fine but the tach didn't move

 

thanks brother, I appreciate it.
