Get out a multimeter and test the ignition wires. Sounds to me like your just looking for a switched 12v.
Here is the wiring layout I used to install my auto start.
DIRECTWIRE™ WIRING INFORMATION - JEEP / COMMANDER / 2006 / Security
[PRINT THIS PAGE]
12volts lt. blue/red (20A) + ignition harness
Starter pink/orange + ignition harness
Ignition pink/lt. green + ignition harness
Power Lock purple/dk. green - driver door module in door
Notes: Lock is negative trigger thru a 330 ohm resistor. Unlock is negative trigger thru a 100 ohm resistor. MUST use relays.
Can also use the trigger wires for the door lock relays
found at the instrument cluster, conn. 2. Lock is lt. green/dk. green in pin 5. Driver door unlock is tan/lt. green in pin 6. Passenger door unlock is purple/lt. green in pin 7.
Power Unlock same as power lock wire
Lock Motor lt. green/lt. blue 5wi plug above fuses, pin 36
Unlock Motor lt. green/dk. green 5wi plug above fuses, pin 35
Disarm Defeat lt. green/tan 5wi plug above fuses, pin 34
Parking Lights+ do not use, relay
rests at gnd
Parking Lights- (CAN data bus)
Hazards white/dk. blue to white/tan - SCM, 16 pin plug, pin 16
Notes: The SCM (Steering Column Module) is in the steering column.
Turn Signal(L) use hazards wire
Turn Signal(R) use hazards wire
Door Trigger see notes - each kick or cluster, conn. 3
Notes: The LF door is purple in pin 6. The RF door is purple/white in pin 7. The LR door is purple/gray in pin 4. The RR door is purple/yellow in pin 5. Use all four wires and diode
isolate each wire from each other and the control module. Refer to DirectFax 1076 for wiring information.
Dome Supervision yellow/orange - any light or cluster, conn 2, pin 12
Trunk/Hatch Pin pur/org and pur/brn (glass) - DKP or cluster, conn. 3, pins 3, 2
Hood Pin N/A
Trunk/Hatch Release orange/purple - DKP or cluster, conn. 3, pin 8
Notes: Meter this wire while opening the rear glass from the switch on the rear hatch.
The hatch release motor wire is orange/gray (5wi) at the plug above the fuses, pin 25.
Power Sliding Door N/A
Factory Alarm Arm factory remote only
Factory Alarm Disarm factory remote only
Disarm No Unlock with ignition and Sentry Key
Tachometer NOT red/tan or dk. grn/lt. grn ac any ignition coil or fuel injector
Horn Trigger dk. green/orange + horn or IPM, conn. 2, pin 35
Notes: The IPM (Integrated Power Module) is on the driver fender, behind the battery.
Memory Seat 1 lt. green/orange - driver door module in door
Notes: The memory seats are negative trigger thru resistors. The resistor
values are not known at this time. Cut the wire and meter it while pressing the memory seat buttons.
Memory Seat 2 same as memory seat 1 wire -
Memory Seat 3 N/A -

Being this is a Chrysler product, they use the multiplex system so your most likely going to have to look elsewhere for your switched 12v then at the ignition. Get that multimeter out and test away.
