Hello all, I ran across something that i'm sure a lot of you can answer but being that Im new I need some help. Ok, I know how to work with the transponders but I when i went to the website of idatalink i noticed it had on the side Door lock, unlock, arm OEM alarm, etc... I was wondering what does this have to do with the idatalink? I thought these connections were for the remote starter wires only that come out of teh brain? My second question is how do you add a relay on a car with only 1 wire for lock and unlock. I came across this for a 2002 Dodge ram:

Power Lock WHITE/ green - driver kick panel

Notes: Lock requires a negative trigger thru a 820 ohm resistor. Unlock requires a negative trigger thru a 330 ohm resistor. MUST use relays.

Power Unlock same wire as power lock

Now, what type of relay do i need and how do i wire it with the resistor? I can get the resister but do i connect the WHITE/ green wire to the 2 resistors and connect the resistor to the relay? if so how do i do it? I love the picture diagrams with explanation but unfortunately there arent much of thise. Any help will be greatly appreciated. Thank you

i am an idiot

In the instructions that the above link will lead you to, I just noticed that he has 820 ohm resistors for both lock and unlock. That is an error, Substitute the 330 ohm for the unlock relay.

If you are using the IDatalink ADS ALSL-CH module or similar IDatalink module, it will do all of the locks/alarms for you thru the J1850 Data connection to the truck. All you need to do is send those outputs from the R/S brain to the IDatalink module. Makes for a much easier install and as an added benefit the IDatalink module can supply the R/S a nice Tach signal and a (+) Brake signal. No need for relays or resistors or finding the Lock/UnLock wire.

Soldering is fun!

One of your questions has been answered but if you don't have access to the by-passes (just install over here!). If your unit has a 6 wire lock/unlock output, then it has built in relays and you wont need external relays. If two wires,then these wil be very low current outputs and won't be able to send a signal through the resistor(s) hence the need for relays to boost the current.

KREG257 So basically what you're saying is that if I just install the idatalink and put the wires from teh R/S to the idatalink i wont need to connect the lock, unlock, tach wires onto the remote starter?

Kind of yes. You won't have to attach wires from the R/S controller directly to the truck for Lock/UnLock, tach, disarm, and brake. And you won't lose a key to bypass the immobilizer. The R/S controller will still connect to the trucks horn, parking lights, hood pin, ground and ignition wires (Battery, Start, IGN's, accessory's). The IDatalink module will handle the immobilizer bypass, locks and alarm for you. It will also supply the R/S controller with the tach and brake signal inputs it needs ( instead of getting them directly from the truck). If you use the IDatalink ADS ALSL CH module, follow the guide. Your truck is Section C, type 3. Make the connections between the R/S and the IDatalink on the bench, effectively mating them, before installing in the truck.

Remember to set the Installation mode of the IDatalink module to either Data of Standard mode before programming it to the truck. (page 26 of the install guide)

For the parking lights, you will need a relay & resistor. Here is a link to the diagram using a Bulldog R/S: http://64.85.6.129/extrainfo/diagrams/17044_RAM-FULL-SIZE-PICKUP-_CHRYSLER%20PARKING%20LIGHT%20DIAGRAM.pdf
