hey guys,

Ihave a 2 part question for you all.

Does anyone know how to modify the wiring to allow your fog lights to be on at anytime, including with the high beams?
Does anyone know how to modify the wiring to allow your low beams to also be on at the same time as your high beams?

i was able to modify the wiring for my 05 trailblazer to do both of these.....But i had to trade it in on a new avenger when i saw them.


thanks,

Paul

 

Normally I would be outside right now splicing wires trying to come up with a solution to that.. But its been raining for the past 3 days here and I haven't had the chance to check it out.. However off the top of my head withoutconfirming with the car electrical wiring I'll see if I can write something up that may help you at least until I get the chance to check out whats inmy car.

I don't actually have a wiring diagram of the car but if its not raining by you then you can just do what I was going to do..

What you will need for this project:
Electrical Wire
2 12 Volt Relays @ at least 30 Amps
( Like this one http://www.allelectronics.com/cgi-bi...VE_RELAY_.html)
(I was originally going to recommend a blocking diode but cant really find one rated @ 30 Amps)

For anyone that doesn't know what an automotive relay does, it allows a small amount of current to control a larger amount of current. It is used in this project for 2 reasons, 1 it will take the load off of the high beam circuit that the low beam circuit will add (Preventing melted wires and blown fuses), and 2 prevents the low beams from sending electricity back into the high beams (You probably don't want your high beams on all the time when you turn on your low beams)

ok, lets get started..

Unplug your high beams, low beams, and fog light on one side of your car..
Get a multimeter and ground one lead to the chassis or negative terminal of the battery (Alligator clips would be useful here)
Turn on your low beams and probe the low beam socket terminals until you finda wirewith 12 Volts.
Turn on yourhigh beams and probe thehigh beam socketterminals until you finda wirewith 12 Volts.

Wire in your relay by following the relay wiring diagram. (Relays usually have a diagram on the side of them or have instructions that show you which terminals do what)
Relays have a switching circuit (To turn the load on and off), and a load circuit (The circuit that supplies the power to whatever it is that you want turning on and off)

Basically you will have the high beamlive/positive wire going to one lead of the relay, a ground lead going to your chassis or negative battery terminal. Which will complete the Relay switching circuit.

Then you will wire a fusedpositive lead preferably to the battery's + terminal to the load terminal of the relay and the last relay lead directly to the positive wire of the low beams. and that will complete the relay load circuit.

The end result will be the relay will allow current from the high beams to switch on the relay's load circuit allowing the low beamsto light up when the high beams are engaged.

You can probably wire in the positive wires of the fog lights as well, so you can really blind someone when you flash them

The same thing can be done with the low beams connecting them to the fog light positive wire so that your fog lights will come on when you turn on your low beams but if you have daytime running lights that should effectively leave your fog lights on all the time which is probably not desirable.

Let me know if this is too vaigue and I will draw up a diagram and take some pics.. I will update this post when I find out the actual wires to save you the trouble of using the multimeter.

 

your low beams dont come on with your high beams hrhitter97? weird mine do/did before i put HID'S in
