2000 Grand Cherokee, Compustar 4900S

Finally getting around to installing this system that I bought a while ago. It has the Blade AL module, and I have flashed it to my vehicle. the wires from the Blade harness - very easy to find and understand. But some of the other wiring has me stumped. The parking light mux wire - easy enough to find the harness on the jeep and ok, put a 1000 ohm resistor in line but.....there are 2 wires marked lights on the RS A heavy gauge green/white in the main 8 pin plug labeled +12V Light, and a smaller gauge wire also green/white labeled -250ma light out (POC #1) which one do I use? also in the wiring table it shows driver's doorpin (for the alarm?) but doesn't show which wire from the RS goes to the drivers door pin. Any help would be greatly appreciated. thanks

The CM900-s is not an Alarm system and is for Auto Trans vehicles only. As such, there is no need for a Door Trigger input wire. You might use a vehicle (-) Door Status wire for RAP Shutdown. For the Parking Light MUX wire, it's a (-) signal through a 1,000 Ohm resistor. You could try the thin Green/White (-) Parking Light wire with the resistor in-line but if that doesn't work properly iDatalink has this wiring diagram with a 5 Pin relay that will work : Soldering is fun!
