Alarm system help?

05ram4x4 · Apr 14, 2013

I'm trying to install an alarm system. I have the main power wires and things hooked up. I can't figure out the parking lights and the door locks.

There was an alarm system installed that didn't fully worked. The doors and alarm worked. It didn't work for starting. I tried connecting to the same wire for the parking lights but it doesn't work. The system I'm installing has 2 wires. One for the parking light output. And a parking light isolation wire. Any idea?

AS for the door locks, I can't even find where the old system connected. Where would be the best place? Do I need relays. I remember having to add relays in my 97 ram. Do I in this 05? I"m sure it's been asked before and I did do a quick search, but none are of these two issues. I appreciate any help.

I attached the sheet that came with the system. It says which wires go where. I just need to find out which wire to connect each to in the truck.

Try the12volt.com they have lots of info.

Ive tried all of those sites. I know which wires. I just need to know if I need relays or anything. I cant find where the old system was hooked in.

I remember having to use isolators on my 04 not sure if its the same for your model...
I will see if I can find any info on it.

try running a 1.7 resistor on the light wires

05ram4x4 · Apr 16, 2013

The thing is that when I connect the wires from the unit to the wire behind the headlight switch, only the cluster lights flash. Not the outside lights. Ill try that next time I have a chance.

Wrong info

canadian kido · Apr 16, 2013

Do you have the brain (alarm) set to positive or negitave park lights? The truck will have both positive and negative park lights. Sounds like you have your jumper on your brain in the wrong placement. Your negative park lights will be at the headlight switch with a wire color of white/light green. ALWAYS TEST, some times the wire colors dont always match up, but 99% of the time they are correct. You will also find your door lock wires in the drivers kick door harness. They both share the same wire color of purple/dark green, like I mentioned before ALWAYS TEST. Lock is negative trigger thru an 820 ohm resistor. Unlock is negative trigger thru a 330 ohm resistor. MUST use relays. Hope this helps.

wait this is an 05 I thought it was a 97 let me look some more.

This is the right info!

Yea, first off I though he was talking about an 97 too. All the info I have provided is for a 05 Ram

05ram4x4 · Apr 16, 2013

The system I pulled out tapped into the white/light green wire at the headlight switch. I tried switching the polarity for the lights and neither worked. (the new system can be switched.) As for the locks...I assume the old system had to use relays too? If so, I never took any out and I didn't see any in there! Unless they are in the door itself. How do I even access the driver kick panel?

05ram4x4 · Apr 16, 2013

Sorry guys. Maybe I should have my name changed!

canadian kido · Apr 16, 2013

pull all the plastic off down in the kick panel. The wire harness will be behind there

05ram4x4 · Apr 16, 2013

The kick panel is where the parking brake mechanism is isn't it? I tried getting in there but that's in the way. Do I have to remove it?

canadian kido · Apr 16, 2013

No, look at this picture...

cmiller0711 · Apr 16, 2013

You do not have to take the p.b. out

05ram4x4 · Apr 16, 2013

I know I have to take that off. I did but the wires go behind the parking brake mechanism. Unless you are saying that I can just tap in where the wires go along the door sill. I thought about that, but I figured I'd try to use what they already put in. If I could find it.

05ram4x4 · Apr 16, 2013

I figured out the lights. For the most part anyway. I'm supposed to actually cut the wire completely and add the alarm system into it. Let me explain.

There are two wires for the lights in the alarm system.
A white wire for the parking light output
A white/brown wire for the parking light isolation

Now the module has a relay inside of it. When I cut the wire in the truck behind the headlight switch, the lights come on automatically. If I connect those two wires to each half, the power is sent through the internal relay and they shut off. If I hit the lock/unlock button the lights flash right. But only the dash cluster lights. Is there a separate wire for the exterior parking lights?
