Remote/Alarm install - parking lamp wire/relay

hunter0781 · **Joined:** Sat Dec 31, 2011 9:23 pm **Posts:** 29

I completed a remote start/alarm install on my 06 CRD sport but I'm running into one small problem that I can't seem to solve...

There is a wire from the remote start that drives the parking lights when it's initialized. They first blink, then once the jeep has started they stay on constantly. I've connected it to to the red/pink striped wire from the headlamp switch on the steering column. When activated it does light the parking lamps but also fires my headlights.

My goal is to only light the parking lamps and not the headlights...

Can someone help me understand how the parking lamps are controlled or where the relay is if there is one?

Any help would be greatly appreciated. Cheers!

What alarm system are you using? Did u try to change the settings on the alarm unit to parking lights only?

I installed the Avital 5103L with an Xpress kit from DEI. I've played with all the settings in the install manual but haven't had any luck. Also, there's a jumper on the alarm for the parking light wire which either sends full current or a 200mA pulse to control a relay...I've tried both.

Any idea how the headlight switch only controls the parking light when it's rotated forward one notch?

Thanks!

a not sure maybe your trying the wrong wire?....also does this alarm have a "high ideal" mode?

I've tried multiple wires...even probed them with a multimeter trying to find the right one...no luck. Every wiring diagram I've found says it should be the pink/red wire.

http://www.the12volt.com/installbay/for ... ?TID=84475 I've also tried a resistor as stated in the notes but still have the same problem.

Do you have day time running lights? Maybe thqtnur problem remove the day time running relay and I bet it will work :BANANA:

also where did you tap the high ideal wire to?

No daytime running lights on my model. No high ideal mode mentioned in the manual so I'm not sure what you're referring to...?

Don't aftermarket remote staters have a feature where it will high idoel to warm engine up in cold? :dizzy:

Yea it has a wait to start feature which is set to 15 seconds.

Again, all I'm trying to do is isolate the headlights from the parking lamps so only the parking lamps light when the remote start or lock/unlock is triggered.

I see can't u just run wires direct to parking lights? That's what I would do... :2cents:

You need to set the jumper for a negative pulse, you also need to use a inline 910 ohm resistor to activate the parking lights.

Thanks.

This may be a stupid question but if I set the jumper for a negative pulse it'll only send a 200mA signal through the wire. I don't believe this enough to fire the lights.

Do I need to use a relay to reverse the voltage from positive to negative then use the 910 ohm resister inline with it?

Cheers!

Yes if your remote started does not have built in relays, which if its a -200ma pulse then it doesn't you will need a 12v relay to send the ground pulse then the resister off the relay ground pulse. If you need a diagram let me know.

Yea it's a -200mA pulse. I'd appreciate a diagram if you have. Thanks a ton for your help.

Cheers.

Keep in mind the liberty needs a - pulse take a look at this diagram. https://docs.google.com/file/d/0B1ndc8rPvN_9UXpUbi1KMmxwSlU/edit

Thanks again. Can you tell me how many watt 910 resister I need? I found a few sizes online...my parking like output from the alarm is fused with a 10amp fuse.

Gokeeper · **Posted:** Thu Jan 24, 2013 8:38 pm

since its a ground pulse wattage doesnt matter 1/4 or 1/8 watt will be just fine. Get one from radioshack most resistors are +- 5 or 10% depending on price point. If memory serves radioshack carries a resistor assortment with a 910 ohm in it. if you cant find a 910 a 1k should work too. (I remember trying one)

If you ant to verify the resistor will work since you have already located the parking wire use a scrap wire and touch a ground with one end and holding the resistor in series touch the parking sense wire and the lights will flash. Remember you arn't powering the lights you are simply providing a input to the sensing wire that tells the factory relays to activate to turn the lights on.

Hope this make sense to you.

One last hint if you experience erratic operation of the remote start or light flashing check your ground. There isn't any metal under the steering column that makes a good ground. I ran a wire to the kick panel and used a self tapping screw after numerous issues in to the unibody frame.

Found 470 ohm at radioshack http://www.radioshack.com/product/index.jsp?productId=2062342&filterName=Brand&filterValue=RadioShack

connect two in series and you have 940 ohm which is fine cost is only $1.49
