Where to connect case power connector pins to motherboard

Not ever had an issue connecting case connector pins to the motherbaord but not been successful with my first Phanteks Enthoo Pro.
The Motherboard is MSI Z97 MPOWER

Just built the system, motherboard turns on from its own power switch and all fans spin, signal goes to monitor. Power switch on case does not power on the system.

There are 2 separate cables for the case, First set with;
POWER LED+
POWER LED-
RESET SW
HDD LED +-

Another cable with just;
RESET SW

The first set of cables plugs in with all pins marked on the adapter that came with the motherboard but there are no markings visible for the 2nd 'RESET SW' pin cable

I have traced to find the cable with the main cluster of pins goes to the power button on top of case
The second cable with jsut the RESET SW pins goes to front panel Restart/reset button

Could it be possible the RESET SW on the main cluster is actually meant to be POWER SW?
and what is the FP PWR SLP pin slot?
