1988 Nissan Sentra 1988 Nissan Sentra

Find the plain black wire at the coil connector pierce it and hook up the Tach there-make sure you disconnect the throttle position sensor/switch and on drive handbrake applied while adjusting it.

I am not sure if it makes a difference, but the car is a 1988, and the picture that you sent does not look the same. I have seen a Nissan Sentra 1989 and they do not look the same Thanks Sean

There will be an idle screw that will show when you start turning on it-which will open the throttle gradually as you turn/look closely. This the TBI unit that I just pulled looks like yours-this is where you adjust. Good Luck

I'm sorry, what my question was, is where do you attach the tachometer on a 1988 Nissan Sentra when you want to adjust the idle? I know where the idle adjust screw is, I just don't know where to hook up the Tachometer. Believe me even the crappy manual does not tell me where to hook it up at (Chilton). I sure am glad I got it free.

Your help is very much appreciated.

You hook up the Tach/Dwell meter to the plain black wire at the coil connector you need to pierce into the wire-
