TD42 oil gallery ports and sump

Gidday all

Im putting in an oil pressure sender and an oil temp sender... have a couple of questions - where are a few good and unused oil ports on the block. Need one for the pressure sender. Thought of using the port where the factory sender is, I just don't want the dummy light on the dash coming as a result. Also where is another good location for the oil temp sender? Was thinking in the sump but would prefer a port so I can avoid cutting the sump some more.

TIA
