ID electrical features of 617

[bricktron]

there are two electrical features on my 617 that i can't recognize. i have a mixture of 1977, 1982, and 1985 W123 parts including some W126 bits so i can't say with authority where these came from. does anyone recognize these guys offhand?

beneath the oil filter housing - with a sender wire installed:



beneath the manifolds - nothing plugged into the tube - 2 conductors are visible in in it:

first pic: must be from a 1981-1985 300sd or a 1985 w123 diesel. that is the oil pressure sending unit to the gauge cluster.

second pic: looks like someone has stuffed a random gasser engine knock sensor into a hose to block off the engine's original crankcase oil separator return from the stock air cleaner. it is fine if it doesn't leak and you choose not to use the original air cleaner setup.

thank you BT, great diagnosis! one to wire up, one to block off.
