I have a 2010 NH C190 that quit on me in the field, the field tech diagnosed it as a bad safety controller, or interlock control relay. I can't find it for the life of me.

Can anyone tell me where it is? I've checked behind both instrument panels, I've pulled the cab liner on the roof, and the wires coming up from the loader controls go in behind the fuse panel in the cab and I can't see a safety controller there. The dealer doesn't know, and all they have are the electrical diagrams that show the controller, but not its location. Just a part of an electrical diagram.

The field tech went through the whole engine compartment and didn't find it.

It looks like it will take 30 seconds to replace once I find it, so frustrating that I can't locate it.

Can anyone point me in the right direction?
 
For reference, this is what I'm looking for.

Confused, when I do a where used on Messicks website for SBA385871261, which I think is the part number for that, it only is shown going into compact tractors, not loaders. And I don't remember those being on the L185's (wheeled version one size smaller) I had. Can the dealer send you the parts diagram showing where it goes? Or give you the diagram number.

The part in the picture above showed on the dealers website as going on my machine, and neither the parts or service department has been any help in providing any info. I did buy the service manual and there's electrical diagrams, but that doesn't show the location. Just where they go in the circuit.
 
Does your service manual have the number 87630288 on it dated 6/6/2007? What page/diagram do you see the shown in the circuit? Hoping that I can relate the possible location to the other items in the schematic that I might know where they are.
Also, does your machine have pilot controls (short levers) or long manual lever controls? And do you know if it's considered an upgraded cab?
