I installed a wideband sensor in my car and cant get it to work. for power I used an add a circuit on the fuse block behind the glove compartment and for a ground I used a bolt next to the fuse block which is visible through the access panel on the side of the dash. I have it interfaced to my computer through the dhp, and I am using the conversion 2(V) + 9.8 in the dhp software. the control box is set up in a way the wire harnesses cannot be plugged into the wrong place.

The problem I am having is that the gauge readout on the dhp constantly says 5. no fluctuation or variation whatsoever. aeroforce says the control box is working fine. any ideas what I'm doing wrong?
