So as we all know our tach sensors are prone to having the wire sheathing split as it enters the sensor and leaving us with no choice but to head down to the dealer and bend over for a new one. Well not any more guys! In a effort to fix my intermediate tach, I set out to find a better way to do this. With some help from other guys on a different forums and a few guys on here identifying wire colors, I installed a new tach sensor for $38. Here's How I did it:
You will need a crankshaft sensor from a GM 2.0 motor. I know, its a GM part but maybe Ford should have reasonable prices. I went down and asked for a 1989 Cavalier sensor. Get the wiring pigtail for it as well. These two came to $38 at Autozone, although most stores were within a few dollars of each other. Then, get a 3/4 x 16 DIE from Napa. I didn't have this so it cost $4.50
You can see it that pic that the new sensor is already threaded by the die, heres a close up. The threads are not exactly the same, as the die is a pipe thread I believe and the sensor is not, but it is damn close.
Next, just screw in the new sensor, its pretty snug, and I used a little thread lock to hold it in place and seal it. I screwed it in all the way to the timing gear, then backed it off a 1/2 turn and it works perfectly. Cut the old connector off and splice in your new sensor. It doesnt matter which way you hook the wires up as its AC current. Hook it up and watch your tach work perfectly!
