G60 swap oil pressure wiring help

Swapping a G60 into my mk1 pickup that had a 1.6 gas originally.  From what I can tell the 1.6 gas only had one oil pressure switch on the side of the head.

The G60 has one on the side of the head where the charger oil feed is, one on the oil cooler and a temp sender on the oil cooler.  

So do I just connect the one on the head and call it good or do I need connect the other pressure sensor as well?  

Assume I can leave the temp sender disconnected for now and add a gauge later.

Thank you
