my buddy just recently put a tach in his 95 4 door civic dx which didnt orginally come with a tach. anyone know what the car redlines at? engine code is d15y7 i believe

 

1992-1995 DX/LX are D15B7
1992-1995 EX/Si are D16Z6
1992-1995 CX are D15B8
1992-1995 VX are D15Z1

D15B7 redline is at 6,400 RPM. Cut-off should be at 6,800 RPM.

then it must be d15b7.. we tapped into every dizzy wire there was and its redlinin at 3500 rpm's? why is this? there isnt any other dizzy wire to tap into?

 

Do not tap into distributor wires.

Behind the driver side strut tower is a harness. Look at it. You'll see a single blue wire hanging there (or under the tape) with a black rubber grommet looking piece at the end of it. It won't be bundled in the harness, it will be just dangling there seperated from the rest. That carries an RPM signal. Tap into there for the RPM signal.
