I'm having issues with interfacing to door locks on a 2010 Dodge RAM 1500. Been probing everything in the driver door and had no luck. I attempting to setup a drivers priority system. Checked search and wiring info on several sites, nothing seems to match this truck.

All the info I found is for a straight all door lock / unlock using the resistor based one wire system at the passanger door:

POWER LOCK      PURPLE / LT.GREEN (- THRU 330 OHM RESISTOR)          SWITCH IN PASSENGER DOOR OR AT LOCK MODULE IN PASS DOOR
                                                                                                                                         PIN 4 ,BLUE 10PIN PLUG
POWER UNLOCK    ONE WIRE, SAME AS LOCK (-THRU 100 OHM RESISTOR)    IN PASSENGER DOOR

Priority UnLock is supported by the iDatalink bypass modules, like the ADS ALSL CH.

Soldering is fun!

I got it done yesterday after probing wires for hours. I used a relay in the driver KP for drivers priority unlock. 09+ trucks are way more difficult than the earlier ones. I need to start using modules instead of resistors, diodes, and relays.
