Hi Folks,

I have a 350HP Cat C7, rear radiator in my Vectra. I just happened to notice the sensor and wire circled in the enclosed picture. It's in between the turbo and the alternator on the driver's side of the engine. The wire has a plug on the end, but it's not connected to anything--can anybody identify it and tell me whether in fact it should be plugged into something?

Following up on my own post, I checked with Freightliner and they determined that it is an A/C pressure switch supplied by Freightliner but not used by Winnebago (at least for my Vectra) because they installed their own elsewhere in the system.
