I need to know what this part is. I went to the local parts store and they/we think it is brake proportional valve sensor. When i was chasing wires on the 7 prong rear plug wasn't getting power i must have bumped it and broke it off, now my ABS and brake lights are on. can i buy just the sensor or do i have to buy the whole thing?

Looking at my Haynes manual it looks like you have to replace the whole combination valve unit. that sensor is called the pressure differential switch.

:banghead: Thanks

I did a little checking about the part and it seems that its just about impossible to find since it very rarely goes wrong, so I'm guessing your best bet would to see if you can get one from a junk yard if you can find one at a junk yard, then you can probably just get/replace the sensor if it just screws out like it looks like it does.

stealer dealer wants $180 for it new, im calling around now at junk yards. Anyone parting out a 1995?

If you can't find anything at a junk yard you could probably get in touch with one of these guys over on cumminsforum that are parting out trucks. http://www.cumminsforum.com/forum/94-98-2nd-gen-all-products/390251-95-dodge-part-out.html http://www.cumminsforum.com/forum/94-98-2nd-gen-all-products/309634-parting-out-1995-ram-2500-cummins-4wd.html
