So I swapped in an 86 motor and wiring harness in my first gen that has a 4 speed manual. And the 86 motor was mated to a 2wd Auto Tranny. So I was wondering if my speed sensor is in the Auto tranny that is no longer being used, or in the wirng harness. And if I do not have in the wiring harness, what could I do to install it in the manual tranny?
