Im going to ask a dumb question. Do you have a book for this vehicle?

Yes sir, I do. I have the big GL1200 book, the SEi supliment and the SEi electricial trouble shooting manual. All OEM. I have been searching the books but so far no luck. I thought is was the TW sensor but appears not to be. The thing has a 2 conductor shielded cable that goes up to a yellow connector under the right side rubber pull up panel that you pull to access the top right shelter bolt. The shielding has pulled free of the unit housing and was taped up by the PO. I just want to make sure whatever the thing is that the conductors are not broken. Looks like some kind of vacume operated switch that screws into the top of the engine block. ?? It is directly behind the air valve..

Thanks, my oil presure display is working so i guess all is well with it. I'll clean and tape it back up.
