M1083A1 - Can someone identify this part please?

Hi Folks,

I have been enjoying the heck out of driving my resurrected Truck!
Got my door handles in today from ebay and they look good.
I also found them direct from the manufacturer, TriMark - $180 (ebay) spent, well worth it. Looking forward installing both of them and making my doors operational.

Here is my question!

I removed the front bumper to look into replacing it, including the headlights.
When doing so, I found in the front left area underneath the driver position something what appears to be broken, but maybe still functional.

Hopefully the picture will be enough for someone to tell what it is.

As always - your guys help is greatly appreciated!View attachment 774522

Assuming that the black part in the lower-left corner of the photo is the steering box, and all the lines, fittings, and valves are under the driver's side of the cab, under where their feet would be, then the switch should be the low pressure transmitter. From the TM -365-24P, Figure 154, part number 6.

After doing some sooper-sloothing, I find that Haldex makes their part BE13241, a low air switch, closed at 0 psi, opens at 66 psi, that should be a direct match. YMMV (your mileage may vary), not responsible for inaccurate results, wash hands after using the bathroom, don't tug on SuprMan's cape (yes, the SS- Suprman), etc.
