XR2WISHY

I am using an early (think it was a G reg) XR2I inlet with the remote mounted ISCV unfortunately the ISCV and pipework had all ready been removed as the inlet was bought from a breakers yard, I have had the inlet a year or so before getting fed up trying to start the RST it on MFI and deciding to convert to EFI. The inlet has a large pipe connection on its left hand side as you look into the engine bay, this I think connects to ISCV but it is the connection on the ali block that has me confused ? is the the one that should go to the cross over pipe ? Just for info the connection on the ISCV looks clean but the one on the ali mount looks oily ?
Thanks.
