95 Z34 here, now driven by baby boy. Washers gave up the ghost. tubing broke off the nipple on the inside of the connector that goes thru the firewall with the wiper wiring. Can't find it listed (or a part number, or it's name). Directly behind the trans dipstick at 11 o'clock. If anyone has the part name or number I would appreciate it!

 

I'm kinda confused what your asking...
Any chance you can post a picture?

 

not sure if it is easily replaceable anyway. years ago mine was broke when a shop replaced my windshield. what they did is drill a hole next to it and feed the hose thru that hole. that stock piece has a harness going thru so it isnt a simple unplug and replace sort of thing
