FW = Fly Wheel

Look down on the drivers side below the oil filter housing, and you can see where the Sensor fits into the adaptor plate.
Has a small bolt that holds it into place.
Picks up the revolutions from the FW Teeth I assume.

The Tach will work with a manual FW also. I swapped in a 4-spd into the 85 and using
the manual FW and the Sensor, everything works the same.

We are advised to NOT judge ALL Muslims by the actions of a few lunatics, but we are encouraged to judge ALL gun owners by the actions of a few lunatics. Funny how that works
