Why is early s2000 not on board, 99'-05'? Or what are reasons?
I have 2000 with rsx ecu and kpro v4.
Unfortunately i bought it already swapped, so im not familiar with everything.
It starts and drives, but alot of coolant line are missing.
1. The 2 iacv lines
2. Lines to throttle body( i know 1 from iacv)
3. another below throttle body
Are all of these deleted or bypassed with kpro software?
I found this diagram also, is this optional or is this recommended

They are not needed and can be left off.

Ok, thank you.
Is there any benefit to adding them or is it just extra work, or extra cooling not needed?

It isn't for cooling; it adds heat for some climates and is completely not needed.
