Item #1 is a temp sensor.  Item 2 looks like a VDO pressure sender that does 
double duty... the body of the sender gets ground from the block; one of the 
output posts gives you an analog signal (variable resistance to ground) to 
send the pressure to the gauge, the other is a switched output to send a 
ground to an annunciator light, probably to indicate a low-pressure condition.
