2007 dodge ram automatic headlights

Hello,

Can anyone help me with the installation of a DEI-545T in my 2007 Dodge Ram.?

I think with the CanBus stuff it's not as easy as it should be.

I want the parking lights and headlights to come on automaticlly.  I think it would be easy to wire this by adding the relays between the headlight switch input and output but then looking at the wiring diagram I don't think I would be able to turn on fog lights since it is a push button on the headlight switch.

I had the dealer activate the daytime running lights but now I want to add the full automatic feature. I really miss this feature after getting this truck

thanks

Steve

I do not have remote start and have no plans on adding it so I'm only looking for the lights to go on once the ignition is turned.

thanks

I guess you lost me with the negative trigger and 660ohm resistor stuff.  Do I need to wire in an external resistor is that resistor in the switch itself?  Also I do not want the fog lights to be on the automatic circuit. I would like to remain as they are..manual control.  Is there any way you could make this really easy on me and show me a wiring diagram of detailed explanation.

thanks, Steve

My DEI545t kit contains the following.

(2) relays (the normal mr76 type with 85,86, 87,87a and 30 pins and a control module the photocell and wire harness plugs into. A prewired harness for each of the realys. According to the instruction sheet one is for the parking light and the other is for the headlight (one has gr and vio wires the other has bl and br but I forget which is which,,,I dont have it here in front of me. I think the violet and brown wires go to pin 87 and they have an inline fuse installed.The  relays also have have a common red wire to pin 86 that comes off the control module. 2 other wires also come off the control module and if I remember they go to pin 85.

thanks for helping me out.  I really appreciate it !

Blue wire from the relay:  This wire you connect to the WHITE/ light green wire at the switch (in between the wire your add a  660ohm resistor) to make it work.  According to DEI the Headlights and parking lights are negative trigger thru this 660 ohm resistor.  If im not mistaken(if anyone can correct me please do so) this will trigger both the headlights and parking lights so the other wires off the relay aren't needed. Try doing it.  If it doesn't then i'll give other info.

Violet wire from relay- This wire you connect to ground.

The rest of the wires from the module is basics like ground, power, ignition.  The violet wire is the one you also need and you must connect to the BROWN / white or brown orange at the wiper motor. 

This is the actual setup and should be easy.. Good Luck

great information. Thanks for your help.

life was easier when everything was just +12v switched wasn't it...but then we wouldn't have all these gadgets to play with.

I printed out your tips and I'll get to work on it and let you guys know how it turns out.

thanks again for your help

Steve
