Like the others have said, oil pressure or oil temp would be a good start. The temp gauge needs to have a hole whacked into the sump (
mine is immediately above the drain plug, where I could put my finger inside and make sure there was nothing there that was gonna get crunched), A nut was then brazed onto the outside of the sump.....I used an ordinary nut, which I had re-threaded to match the 1/4" NPT thread that VDO senders use.
If you go with the oil pressure gauge (2nd option IMHO, as you already have a warning light, but I would be hooking a buzzer to the light at the least.....but it can get annoying as it sounds everytime you start the motor), then I would mount the sender unit in a different location.
Mine is mounted on the passenger's side of the block, just ahead of the engine mount, and just behind the air-con compressor. This way, you have a second point on the motor where the pressure is being monitored (as the OE light sender is mounted near the dipstick).
Another option altogether, is to mount a voltmeter ....switchable between your 2 batteries (assuming you have dual batts of course).
