S14 "power plug" connector pinout

hi, i’m having trouble finding a pinout for this connector, i’ve been searching around with no luck so far. it’s the big white plug (about 30 wires in it) that is closest to the ECU on an S14 engine wiring harness.

this is a picture of one cut off of a harness:

i need to know which wire does what for a project i’m working on, any help is appreciated.

thanks.
