i have a screen image of the waveforms on all 3 wires @ key off ,key on and running
i will attach the 3 images at running on this post
pin 3 signal wire to ecu
even with the key off and out of ign all 3 wires show 0v then a spike of 5v every 2-3secs which can't be right .
but have noticed the red power light on the adc- 212 flashing ,
