NOTES:
NOTE: For the 2002 Ram 2500/3500, refer to the 2001 techsoft sheet.
NOTE: Chrysler vehicles that use a gray ignition key have an immobilizer
system that needs to be bypassed when remote starting. Use DEI part number
555C or 555U.
*1 Lock requires a negative trigger thru a 820 ohm resistor. Unlock
requires a negative trigger thru a 330 ohm resistor. MUST use relays.
*2 Parking lights require a negative trigger thru a 330 or 1.4K ohm
resistor. Headlights require a negative trigger thru a 1.8K ohm resistor.
There is a rest resistance on the wire, so MUST use a relay to isolate away
from the switch.
*3 The LF door trigger is tan, and the LR door is tan/orange or
PURPLE / orange. These wires are in the driver kick panel. The RF door
trigger is tan/red, and the RR door is tan / YELLOW. These wires are in the
passenger kick panel. Use all wires and diode isolate each. See directfax
document #1076 for wiring information.
*4 This will also do door locks. Arm/lock is negative trigger thru a 2K
ohm resistor. Disarm/unlock is negative trigger thru a 480 ohm resistor.
Single pulse will do disarm without unlocking the doors. Unlock requires a
double pulse. MUST use relays.
*5 The PCM (Powertrain Control Module) is on the passenger side firewall.
*6 The amplifier is located behind the glove box.
*7 These wires may not be necessary for remote start.

I also am also doing a 2002 Dodge ram, putting a APS995A. Audiovox says all door trigger is brn wire in pillar B, but there is no brown. So I was quit interested to see this info. I had already figured out the left doors' wires. Where do I get more info on directfax document#1076 as mentioned in footnote 3 ? Also, my Dodge here is 4.7 engine with individual coils. Audiovox says to hook tac wire to any injector (to the non-common wire). Does this sound right? ------------- charles

door is brown in driver A windsheid pillar you can also get this on the top left are under the guages when the bottom dash panel is removed. that way you dont need to pull the pillar garnish panel. ------------- Joe O'Byrne

Thanks Joe, about the brown wire. Can I hook this to the neg door trigger or do I need a relay?
