    So I have an obd2b motor in an obd2a car. Where can I connect the blue wire to get my tach, as I elminated it when I cut the harness to adapt to my obd2b distributor. I know everyone says search or look at the ecu pin outs, but I've been searching for days and the obd2a (ecu I am using) pin out diagram dosn't have a tach pin. Can anyone tell me how they did this?
