    @sunnyjay what are your grounds like, that could be why your test didn't work. I should be able to scope later this week for you but my notes had this base down as a TTL signal with varied pwm.

    I followed the pin-outs from the above imagine.

    Pin 2 ground - I have all of them linked together to body ground.
    Pin 4 ground - I have them linked to valve cover grounds.
