2003 dodge ram 2500 alarm/remote start

Hi,

I have a 2003 Dodge Ram 2500 and I am installing the 5100rs from Scytek. I can get my lock to work and door triggers no problem, I can not get the unlock to work. Do I need 2 relays for unlock. I really do not understand double pulse. Can this be explained to me. How do I get the nlock to unlock on transmitter.

I got that part no problem I have split my power door wire with 820 neg and 330 on unlock and I tested each wire by grounding relay and I would touch the wire on relay one by one to get the lock to work and unlock to work.

Now this is where I am overthinking, how do I configure both wires on each relay to work.

Does the truck have factery "door" security....if so, double pulse. The first pulse disarms your factory security... the second unlocks the doors, if no factory security, single pulse is all thats needed. Use 2 relays, one for lock, and one for unlock. You can put the resistor in line off of pin 30, or 87....matters NOT.

Thank you KarTuneMan,

I wired up the lock on one relay not a problem, it is my unlock I am having trouble with wire hook up, ca you show me a pic, it would help me. This truck does not have a factory alarm, for door locks.

Thanks auex,

I have always learned from pictures, that is just me.

I am not a security expert like you and I know it probable drives you nuts to repeat diagrams over and over but really, you have helped me a great deal and if you need advice on anything to do with reeftanks let me know, I am a long time reef forum expert and I will donate to this forum

so auex....you,ve done a thousand of these without factory security?

I have a couple of questions about remote starting.

1) I have on order for my truck the 555c by pass module coming on monday and will I need any relays for this application and how should I connect correctly

2) As far as programming that I have read here in this forum, what is the correct way to do this.

I need some help please.

I have looked all over this forum and I can not find my starter wire for remote starting

Where the heck is it or how do I wire to it.

2003 Dodge Ram 2500 4x4 Cummings.

So how exactly is this guy gonna get in his truck with the unit he has....if he does NOT double pulse the wire???

I am VERY curious. Do you know something that DEI, astroflex, or any other tech support doesn't

Does this mean not to use or what does NOT mean

Thank you

Thanks, so I will hook up my alarm remote starter + to the yellow to get the starter to crank?

I see so many posts with ppl doing first time alarms/RS and I hope you are all testing the wires with a DMM or something to make sure you have the correct wires.  Please don't just take the tech sheet as gospel and tap those wires.  Make sure you have the correct wire by testing it properly.

We had a customer who was a mechanic by an alarm from us and wanted to install it himself.  We gave him a tech sheet.  He installed the alarm without testing wires.  I can't remember the car, but he had a + and - park light.  Directechs had the park light polarity incorrect on the tech sheet.   He came back cause he tapped the - park light and sent 12 volts through it.  The park light wire fried all the way to the fuse block becuase he was dangerous enough to pop the 10A fuse a couple times, so he put a 30A fuse in to keep it from popping. 

I know what you professionals are saying. I always take my cars in to a shop for anything, I have 2001 durango (wifes) and my 03 ram. I have had 2 high end stereo systems installed (custom) and even my first alarm system. But my installer and all of them are very busy this time of year so I really wanted to give it a try and this is why I am here.

Believe me, I would not recommend anyone to install an alarm themselves. I do not care how smart you think you are, professionals do it daily and have a comfort zone and can do it faster and cleaner than someone doing it at home, anyday. With that said I really took my time on this self install ( 3 days). I have tested and double tested each and every wire before connection. I have done this step by step with the help of this forum, and ONLY from this forum. I will make a donation too.

Will I do it again, Hell no. I like to fiddle fart with my rides but installs,no way.

Now one last question and I am done, I just need this help. Tach wire on 2003 Ram cummings 4x4.Which one is it. Thanks

What exactly happens if you only single pulse?  Does it not unlock at all or does it just unlock one door?  On my 1999 Maxima, one turn of the key in the door unlocks only that door, 2 turns unlocks all of the doors.  If I don't set it up with double pulse, will I have to hit the unlock button twice on the transmitter to unlock all doors?  Once to unlock only one?   Thanks!

e.n. :)

DODGE, RAM PICKUP, 2003, Factory Alarm Arm
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.
Can also use Directed 457C or 456L interface modules.

That is what I thought, Thanks.

I am still having a tach wire issue. I can get my truck to remote start but I need the tach wire so it knows it is running.

I tried the GREEN/ orange nothing. Can anyone help me on this, which one is it on a 2003 ram cummings

I need the pdf or diagram or color of an A/C-Heater wire for a remote starter on a 2003 Dodge Ram Cummings 4x4.

Thank You

I have everything up and running on my car security system and remote start.

2003 Dodge Ram 2500

I have 2 wire left , 1 of which I need for my A/C to operate during remote start up, and it goes like this as instructions states:

Brown Wire: Second ignition Output(+) The brown wire provides +12 volts for a second ignition wire. This  wire may instead be programmed for use as a second accessory  or second starter wire.

Orange Wire: Accessory Output(+)  Connect to accessory wire coming from the ignition switch that supplies power to A/C-Heater.

Now I have tested the orange wire in remote star and no power comes out, Does this mean I need a relay to supply the 12 volts or does the brown wire play a role in powering up the orange or how do I get my A/C to run during remote start up.

I know there is someone that knows the answer. I am sure a relay is involved to power up my A/C on the steering colum but I do not no which one, I really do not want to keep screwing with it and blow my air bag or something guys, please healp.

No more do it myself after this, my normal installer who does our cars and security has been pretty busy this time of year and I just thought well it can't be that tough. I always recommend professionals and I really do thank you guys for helping me. Now I did acually hook the acc(+) wire to the main ignition harness one by one and the only thing I got was the defrost on the 1 of 3 BIG wires (green) the other BIG wires are blue and pink/blk.

There are some smaller wires on another loom but I figured it is the air bag or ?. But I would think if you use one of the wires the whole Acc/Heat ect should work. Not just the defrost

Now with remote start in action with no ill effects my last and final task is the engine kill relay.

How do you wire the relay without popping a fuse.nI know how to wire up rely w/diode but where do I place the 2 starter wires on ignition switch wire. Do I go above the remote start wire or both below. If the alarm is set and you remote start how would it work

I am wondering what the heck is going on. I drive a little ways and you can hear the door locks trying to lock. It happend when I am coming off a red light or stop sign and as soon as I give it gas you can hear the locks. How can you make this not happen. It seems like it is picking up voltage and when it hits a certain speed they try to lock

Check your ignition wire.  If an ignition wire is improperly connected, then your alarm would disconnect/reconnect with voltage which in turn can cause your locks to lock and unlock.  Also if the polarity on your lock wires are negative switching then they may be pinched or grounding out.

 I checked connections, and they are tight. It has something to do with voltage I am thinking this because when you hit throttle from a dead stop you can hear the locks
