Hello,

Does anyone know if there's a single wire that indicates if the key is in the ignition switch (in any position)?
I tested both the VIO/BRN and PNK/WHT wires coming from the ignition switch and they were as follows:

VIO/BRN (Ignition switch sense):

• No key: 1.1V
• Key inserted (position 1): 4V
• Key inserted (position 2): 2.16V
• Key inserted (position 3): 1.1V
• Key inserted (position 4, vehicle starting): 1.1V (0.3V during starting)
• Key removed: 4.6V for few seconds then back to 1.1V

PNK/WHT (Ignition switch out):

• No key/key inserted/position 1 and 2: 0V
• Key inserted (position 3) 12.3V
• Key inserted (position 4, vehicle starting): 14.3V (~10.6V during starting)
• Key removed: 0V

I'm attaching a security device that needs to detect if the key is inserted, so ideally a single TTL level wire would be great.
The jeep is 2013 Sahara unlimited.

Many Thanks
Maxx
