I have a 94 civic del sol with a d15 motor. 1st my cars interior is all gone except seats and str. wheel, no dash no gauge cluster,no harness . I want to hook up my aftermarket tach, to the rpm/tach signal wire from the ecu, but i dont know which one. don't just say the blue wire it won't help. I need a pinout diagram and wire location.
thanx

You do not need to go to the ecu for the tach install.
There is a blue wire al by iteslf over by the master cylinder........Most have a plug on the end with a black rubber thing holding it in place.
It will not be connected to anything.

^^^ READ BEFORE YOU POST. He said that he removed the wiring from behind the dash and gauge cluster.
