Oil filter housing question

[BurntBisquit763]

What lines are supposed to go into the housing? I know there are coolant lines that cool the oil but what are these supposed to go to?

Top piece is not stock.

Sorry to thread-jack
I am also curious on how the stock lines are routed since a couple were sliced on my 1JZ.

Looks like a filter relocation piece to me, but something still seems off... then again, I've never put on a filter relocation setup, so...

It might be a source for something like gauges (one for pressure, the other for temperature). Doesnt look familiar otherwise.
