I just bought a 2 way Python Responder 460 (3305P) to self install in my Half Door JK (no power windows/locks). It was essentially the same as the Viper (3305V) but I found it online for $40 less.
Regarding wiring, the alarm came with wiring instructions for the brains. JK specific wire locations are easily found online.
I'm tapping into the following linies
+ Light Flash Output, White/Purple (Passenger Side Kick Panel)
- Instant Trigger Inut, Hood Pin Wire
+ Door Trigger Input, White/Yellow(Passenger Side Kick Panel)
- Chassis Ground, Unswitched Cigarette Lighter Ground
+ Switched Ignition, Switched Cigarette Lighter Wire
+ Siren, Siren Wire
+ Constant Powerm Unwwitched Cigarette Lighter Wire
Dual Zone Proximity Sensor (508D) plugged into brain.
Only 5 wires to tap into at easy locations.
Save yourself some money and buy the Python and install it yourself
