- hi guys and girls i have just brought a 1987 75 pick up= sick rig lol any way very happy with it but only issue i can find is the tachometer doesn't work. i know its had a heart transplant it use to be a 2H and now its rocking a 1hz from a 100 series. i have found the sensor + wiring on the side of the injector plug but nothing is plugged in to it. i also know the 2H had a rpm pick up in the bell housing (Hall sensor) i just need help with matching to 2 up and i know people have done this conversion before and im sure they know how to fix this but i dont know and i really want it to be 100%
