Hello All, I am a long time reader, first time poster. I appreciate all of the information that I have been able to gather from this site for troubleshooting over the years! I have finall found something that I exhausted the search functions and my time limit on.

I installed a Ready Remote remote start system. All is well, but I wanted to utilize their headlight activation feature. They did not cover this in their installation guide, but I found other information out there to hook in to the headlight switch with a relay and 1.8K resistor. It works, but the remote start module only has two options, daytime running lights and light your way (lights stay on for 25 seconds after ignition is off). That is great, except that it is like turning the lights on at the switch (parking lights, dash lights, fog lights all come on). With the light your way feature, the warning dinger goes off every time I shut off the truck and get out (it thinks the switch is on). I don't like this, and furthermore am afraid I will actually leave my lights on once I get used to it.

How can I hook into the wiring to activate only the headlights (like the factory delay if you shut off the ignition and then the lights)? I am thinking I should be able to splice into the high beam wire coming from the steering column, but I don't know what resistor I need. Per a service manual I have, it looks like it might be a 20 gauge violet wire with an orange stripe that runs the high beam?

I also thought about a relay under the hood, but the headlight seems to run off of the FCM?

Hopefully someone can help. Now that I am signed up I look forward to helping others, as so many of you have helped me without even knowing it.

Thank you,

Joe

 

Sorry, it is on a 2003 Dodge Ram 2500.

I think you ned to contact a different forum for your answer. Such as a remote start/alarm place like this
Not many guys on here are car alarm/remote start specialists. Most don't install their own stuff either. I have, but even what your asking is model year specific and there are different ways to go about this on a Dodge that I am unsure. I believe you would need to grab the wires under the hood and you can install a remote shut-off timer yourself if you wanted(555) that will turn them off automatically. Again, specifics???? Wrong place to ask.

You need to be very careful which wires you tap into as there are multiplexed wires and you can make some costly mistakes.(mostly inside the cab..., such as, at the switches themselves)

 

Yeah, I am afraid of making the costly mistake, that's why I am reaching out...lol. I know the remote start module's outputs and everything. If I just knew what wire and input was required to activate the headlights alone... Bright or dims wouldn't matter to me. Was hoping with all the discussions regarding having the brights and dims on together, fog light jumpering, etc. that somebody would know the correct wire and input required.

Thanks,

Joe

 

Although I have never done this myself you could do it with two realys. But you will have to cut the headlight harness after the TIPM. You can choose Low or High beam as it would be the same.

For each headlight wire them up like this:

30 to headlight side of cut wire
87a to TIPM side of cut wire
87 to battery (through a fuse say 15A?)
85 to your remote start headlight output
86 to either ground or to battery (through a fuse) it depends what polarity your remote start outputs

This way your headlights will work normally as 87 and 87a are NC (normally closed) contacts when not under a remote start.

 

Thanks for the reply. I was pondering going about it that way. Maybe I am just lazy or cheap, I was hoping to be able to do it under the dash. Looks like I might have to do it under the hood though... I did find somewhere that a 700 ohm resister turns on just the headlights at the switch (I am using a 330 ohm for the parking lights and a 1.8 K ohm for the headlights (which turns on all the lights (fog, parking, and headlights))). I might try that and see if the warning buzzer still goes off with the 700 ohm resister...

Thanks again,

Joe
