My mystery power steering reservoir

[TypeXFan]

I have a 1991 240sx SE came fully loaded, HICAS, cruise control, abs, power everything, no cup holders, etc. Ive been restoring/repairing the car for the last 8-9 months or so, finding replacement parts off the junkyard and local people parting out their S13's. One thing I havent been able to solve is my power steering reservoir. EVERY other 240sx I look at has the standard reservoir, why is mine different? Why does mine have a cap with a sensor attached to it? It's been buggin me because the sensor is cut and I have been looking for a replacement and cant find it anywhere. It has the 2 main lines running out the bottom, but it also has 2 baby lines running out the side of it.

If anyone else has this and has an explanation for it please let me know.

Here are some pics.

ive never seen that on an s-chassis.. maybe im just dumb, but is it possible that someone lost the original cap and replaced it with one from another vehicle?

That was my best guess, I was just hoping that someone on here could have confirmed that for me. I just found it odd that I havent come across one yet.
