    1990 7.3idi E40D tach not working need help

    I am trying to find the relay and I cant seem to find it, I did find two plugs between the coolant tank and the fart can that have red ontop of the plugs, there are no relays plugged in but they look like a plug that a relay would go into.

    1990 7.3idi E40D tach not working need help

    I have a 1990 Superduty wrecker 7.3 auto with tach not functioning and trans in limp mode. I checked all fuses, all good. I replaced tach sensor with new one made no difference, my question is does anyone have a wiring diagram so I can find what wires to test to see where I am losing signal...
