Front oxygen sensor

I have a 207 ultra clasic ,the engine light came on .the code is p0134 which says front oxygen sensor is inactive.Now following the wires from the front sensor it comes to a harness between the front frame tubes, right by the cross brace.this harness is unpluged and as for as I know always has been.the enginge light just now started to come on with this code.Should I plug it together.or is it more than that? thanks

I would plug it back up and see what happens. If you have a Power Commander installed you need a O2 eliminator plug on the unpluged O2 sensor.

the 02 plug goes on the front and rear.and the harness stays disconnected.this is the set-up if you have a power commander,which I do.now I'm thinking it can only be a mappin problem or the pc111 went bad
