Working on my harness, have a few questions This is an '00 harness.
If I'm going to be running an aftermarket fan, do I have to use a PCM activated relay or is a switch fine?
Fuel system will be (2) 255 lph pumps. Again, should I have to PCM trigger the pumps?
Clutch Anticipate Switch Signal 32 Blue- This is a 6 speed car, is this needed/what do I do with it?
5V feed 46 Blue- A on C230.. What is this for? I can't find a diagram that is specific.

Why?
I would wire the fan and fuel pump to the PCM. Best way to do it IMO.
Fan is a switched ground from the PCM, fuel pump is 12v.
Just wire 2 relays, one for each pump and you should be fine. Some people run the second pump on demand by a boost switch, nitrous switch.... You obviously have some plan if you're going dual 255's.
The clutch switch will throw a code if not hooked up or turned off in the PCM. I don't have one hooked up and I get the code occasionally. It's on my list of things to do, but doesn't seem necessary. Never got a good answer on what it really does.
