Wow, loaded question!
Well, it all depends on what devices are on and/or what mode the computer is in to determine which pins should be hot or not. For example, C2 pin 12 will be hot after the ignition is switched off....
Here are some others (once again some may or may not be hot depending on what's on):
C1 pins 5 and 6 should be 12volts
C2 pins 3,4,6,9,11,12,14 should be 12volts
C1 pin 3 should be 0 volts (ground)
C2 pin 7,8 should be 0 volts (ground)
Alternatively, you should be able to test certain devices through these plugs with the Jeep off. For example, supply 12volts to C2 pin 11 to test the shift lamp. Just be sure to Never put 12 volts to a ground wire or C2 pins 1,2, or 15
Hope that helps you
