which port to use for the oil press.

[Eclipse90GSX]

hey guys, i replaced my 90 motor with a jdm motor, but the guy didnt put on the oil pressure sending unit on the oil cooler housing as seen by the pictures.
i cant find the sending unit now and i was wondering if i should get the unit from a 90 or a 91, or if it matters.

which of the 2 ports does it plug into? the top wire is the dummy light, but i cant remember which port to use, the top one or the bottom one.

here is what it looks like

You would use the upper of the 2 for oil feed line for the turbo so I guess it will work for oil pressure sender also.

I would swap out your old 90 OFH - & Why aren't you using the Air to Oil Cooler that came with your 90?
