My grounds:
heater is going to chassis ground, calibration wire is going to diff chassis ground and the rest are grounded through the EGR harness to the pcm (I think). Should be fine since it was working perfectly until I changed the output.
only the one of the analog outs (yellow & brown wires) should be hooked to the EGR. Not both though, one or the other....also, the blue ground should be wired in a seperate location from the other ground wires to reduce analog noise....
