Hello everyone,

I bought the 12 volt installation CD and I cheked the wiring code for my Dodge Grand Caravan Sports. It looks to me that it is complicated to install my remote start w/alarm because of the possibility that my van is equipped with a Transponder Theft System. If it is not complicated, I just have top the wire, use some relays and transistor if possible. Any suggestion is greatly appreciated.

Thank you.

Hood Pin PURPLE / lt. blue   -   conn. 3, pin 30 @ BCM
Notes: The BCM (Body Control Module) is in the driver kick panel near the parking brake. It has 5 plugs in it, one 6 pin plug and four 34 pin plugs.
Trunk/Hatch Release PURPLE / tan   -   conn. 2, pin 6 @ BCM
Notes: Hatch release is negative trigger thru a 1.69K ohm resistor. MUST use a relay.

The BCM (Body Control Module) is in the driver kick panel near the parking brake. It has 5 plugs in it, one 6 pin plug and four 34 pin plugs.
Power Sliding Door PURPLE / blue   -   conn. 3, pin 1 @ BCM
Notes: Left power sliding door is negative trigger thru a 1.5K ohm resistor. Right power sliding door is negative trigger thru a 2.7K ohm resistor. MUST use relays.

The BCM (Body Control Module) is in the driver kick panel near the parking brake. It has 5 plugs in it, one 6 pin plug and four 34 pin plugs.
Factory Alarm Arm PURPLE / lt. blue   -   conn. 3, pin 14 @ BCM
Notes: Arm is negative trigger thru a 1.5K ohm resistor, this will also lock the doors. Disarm is negative trigger thru a 9.1K ohm resistor, if use double pulse this will also unlock the doors. MUST use relays.

The BCM (Body Control Module) is in the driver kick panel near the parking brake. It has 5 plugs in it, one 6 pin plug and four 34 pin plugs.

Can also use Directed 457C or 456L interface modules.
Factory Alarm Disarm same wire as alarm arm
Disarm No Unlock
Tachometer     ac   ignition coil pack
Notes: On the 2.4L use blue/green or blue/tan. On the 3.3L/3.8L use blue/green, blue/tan or blue/orange.

Thank you so much for your tip and information. This will save me more time installing my remote start. I hope to get more tips from you guys. Again, thank you Mr. thepencil.

Hello everybody,

Before starting installing my remote car alarm, I want know how to test a wire that has a negative trigger for example; My starter wire has a negative trigger of 180 ohm reisistance. How can I test it? Is this one of the reason why I have to use a relay? Thank you in advance.

Hello,

I'm still green and don't really know about wiring. I have already a wiring information for my van. My second starter wire is negative trigger thru a 180 ohm resistor, power lock is negative trigger thru 5.3 K ohm resistor, and unlock is negative trigger thru a 2.0 K ohm resistor. Do I have to use a relay for each one? Where can i get the diagram? Is it because of the negative trigger that is why I need to use a relay. Thanks in advance.

Well you obviously have one of the chrysler minivans and this is how it works.

Your starter relay gets wired: 86 12 volts, 85 -starter output, 30 to ground with your resistor and 87 to the starter wire.

You have whats called "one wire door locks", which means you need two relays and the proper resistor values.

Relay one is wired 86 12v, 85 lock wire, 30 ground, 87 lockout put with resistor

Relay two is wired 86 12v, 85 unlock wire, 30 ground, 87 unlockoutput with resistor. once these are built send both outputs to the PURPLE / green door lock/unlock wire in your car.

Thanks for the information Jason. How do I know what ohms do I have to use for the resistor.

IMHO, usually if you have to ask how to test wires, it is best to seek out a professional for the job.

That Caravan is not the easiest vehicle to work on and would be a PIA for a first time learning experience.

I have seen so many DIY alams/RS come into my shop that only half worked because ppl were frustrated and gave up/or couldn't figure everything out. A full working RS/alarm is better than saving $100 and having a half assed fire hazard under the dash.
