Hi,
(C) hose should be connected to compressor housing OR to intercooler cold side OR to inlet maniflod.
(it is an recommandation of Ford Motor Sport in one Performance New bulletin dated of 88 year for grA RS)
Why ? For the same reason that you fit your Dump valve on cold side IC, because air temperature is low on this side. And it is good for the valve AMAL durability.
