Answer 1

Make sure the MUX output is NOT connected. This is the GREEN/RED wire from the EVO-ALL 20-pin connetor. It should not be connected on the Wrangler.

Hello,

yes, from 20pin connector only the yellow cable for ignition is connected.

Only time I see this issue is on vehicles over seas.

We have not tested those vehicles as the computers are not flashed the same as their north american counterpart.
