Is it remotely possible to install a oil pressure sender without a oil change?

Just installed and ran the wires for this gauge but dont want to wait for the next oil change to install the sender. Besides letting the car sit over night to get the oil nice and cold are there any other tricks to install the sender and not lose oil?

Any open ports above the oil line inside the engine?
Any oil sensors above the oil filter/ pan I could T off of?

Thanks guys!

What engine? On both, if the oil settles in the pan and filter, all you will loose is few drops worth.

my bad 30v, So I could T off of the OEM sender if the car has sat over night? Sweet deal.
