hey guys got two questions firstly pretty simple for the remote oil filter people which one is what rearmost pipe in and front out or vise versa? did look when sump was off but misplaced my notebook so yeah now im stuck lol

secondly does anyone have a pin out diagram for the variations of maff sensor plugs ??
there a few varients ls1 was 3 pin with seperate air temp sender?
but mine is 5 pin and a larger type of duetch style plug i got supplied with
compared to another 5 pin thats a smaller plug thats on my loom
basically i got loom from a sports pick up maloo ute (l98?) but engine is from the slightly lower spec ss thunder ute (l76) both are 04 models
i need to wire the new plug onto my loom in correct sequence.
any wiring gurus or threads with pictures available ?
