Have Ford Questions? Ask a Mechanic for Answers ASAP
What Ford Model is this on?
Did you remove it? If so, could you take a few photos of where it came off?
I see a number on it, what is that number?
That number was no good. How about some photos of where you removed it?
Another thing, are them hoses or were those hoses filled with coolant, are they exhaust hoses, vacuum hoses, heater, etc?
Perhaps you can have better luck then me, this is about the only site I search for ford parts and ford parts diagrams, http://www.fordparts.com/Commerce/CatalogResults.aspx?y=1996&m=Ford&mo=F-250&initSearch=1&partNo=9C491#Search
new expert here, How many terminals does this unit have? where the plug goes?
Ok, what you are looking at is the low vacuum warning switch, It is on some of the diesel engines and is used to inform the driver that the vacuum pu,p is getting weak and is reading under 10 hg of vacuum, It does NOT have a low vacuum light, it uses the rake light and illuminates it if the vacuum goes low as could be dangerous if vacuum drop could lose power brakes, Diesel engines use a vacuum pump as they dont produce their own vacuum, soo here are a couple links, One is the wiring diagram, Look close at the note alomng side of the vacuum switch on the right in the diagram and.. a link showing what it looks like on a truck, It is nothing 911 required, it is only a switch to tell driver vacuum went low, that is it, where to get? it will be a dealer item only, I am not in parts, cant help with that, only answer your question as to what it is
