Whaddup man! Looks like you did your research on this install, much respect!
I did a quick search for the 502 manual, but didn't find it. I gotta have the descriptions of some of the wires in the 4, 6, 12, and 7 pin connectors.
This is what I have now:
Door Lock Plug (White 3 PinS Plug)
BLUE (UNLOCK (-) ) = To GMDLBP blue (unlock input -)
RED - not used
GREEN (LOCK (-) ) = To GMDLBP green (lock input -)
*OMEGA DB-GMDLBP
BROWN(NEG GND WHEN RUNNING) = ?
GREEN(LOCK INPUT) = 502's 3 pin
BLUE(UNLOCK INPUT) = 502's 3 pin
VIO&WHTE = not used
VIOLET(DATA OUTPUT) = PURPLE WIRE(OBD2 CONN)
PINK&WHTE(DOOR TRIG OUTPUT) = GREEN wire in 502's 7 pin
PINK = not used
ORANGE = not used
RED (12v CONSTANT) = can wire into constant with RED in 6 pin
BLACK = ground
*6 PINS PLUG (ALL CONNECTED TO THE VEHICLE)
GREY(ACC 1) = (C201) D1 ORANGE
BROWN(STARTER) = (C201) C1 YELLOW ( CUT THE WIRE FOR ANTI GRIND)
*I don't cut yellow, our trucks have anti grind built in*
BOTH REDS(12V) = (C201) D2 RED (C201) B5 RED&WHITE? ( DO I HAVE TO USE BOTH D2 & B5 OR JUST ONE OF THEM?)
You'll use both D2 and B5, but I have to see the manual before confirming which goes to which.
PINK(IGN) = (C201) C6 PINK
PINK&WHITE(SELECTABLE:ST#2/IGN#2/ACC#2) = (C201) C5 WHITE
(this will be set to IGN 2)
*12 PINS
WHITE&RED(TACH ENGINE MONITOR) = WHITE @ PCM BLUE PLUG#49
BLACK(GND) = MAIN GND
WHITE(-500mA/+10Amps) = ?
(should be park lights, have to confirm)
RED/BLACK(10 Amps FUSE) = ?
(need description)
BROWN(SIREN) = SIREN FROM STARTER
BROWN&WHITE = NEEDS A RELAY TO FACTORY HORN?
(need description)
BLACK&WHITE(DOMELIGHT) = RELAY =
(NOT NEEDED, BCM controlled)
GREEN&RED(TRUNK POP RELAY0 = N/A
YELLOW&BLACK(OEM ARM) = NOT NEEDED?
(correct)
ORANGE&BLACK(OEM DISARM) = NOT NEEDED?
(correct)
ORANGE(- ARM ) = STARTER KILL RELAY
*YELLOW(86) = GREEN OF 12 PINS
*WHITE(85) = (C201) C6 PINK
*GREEN(30) = (C201) C1 YELLOW (CUT) OTHER SIDE
*GREEN(87) = (C201) C1 YELLOW (CUT) MOTOR SIDE
BLUE&WHITE(PASS DOOR LOCK) = ?
(not needed)
*7 pins
WHITE(+BRAKE SWITCH) = BRAKE PAL ( WHITE WIRE @ FLASHER)
(correct)
BLK&WHITE(START ACT/HAND BREAK) = ?
(If this is the park/neutral safety switch, I just ground it. Our trucks can't start if not in park)
PINK(WAIT TO START/CAR JACK) = ?
(not needed)
PURPLE(+DOOR SWITCH) = ?
(not needed)
GREEN(-DOOR SWITCH) = ?
(to gmdlbp)
BLUE(-TRUNK SWITCH) = N/A
GRAY(-HOOD SWITCH) = HOOD SWITCH
You did pretty good! There are still some things that I want to be sure of in the connectors that I mentioned above. I think I noted all of the circuits that I want to know more about. There should also be a ground when running circuit in one of the connectors of the 502.
Some people don't wire in acc2, whether or not you want to is up to you. In awers thread, he showed the acc2 relay. I think you can use the violet/white in the 4 pin for your acc2 relay turn on.
I tap into the park light + wire (brown) in the FAP harness for park lights. This is the only way that I found that the headlights won't flash.
