I want to add day time running lights.
I have a 2001 EX.
It appears the DRL MODULE is for 2002 and up.
Any input on how to add day time running lights.

Is there a relay I can purchase to run the fog lights (off of the ingintion) without turning on the lights?

The DRL module is done via a resistor and a relay so that is pretty easy to wire up I can make up a diagram if you would like. The only way that i can see to run the fogs by then self would be to wire them to a seperate switch.

 

Thanks for the reply

JcWhitney sells a low beam light kit (HAMSAR) model.
$80.00
If I can put it together for less, then YES, a wiring Diagram etc. would be appricated.

I'll feal safer with the low beams on while my better half and kids are out in HER truck.

I'm also thinking about the 9500 bulbs for fog lights and the Sylvinia X brightstar bulbs.

I prefer the white stock light color but want more intensity. (20%) more brightness ?

Any input on this would also be appricated.

 

Wire the fogs through a Bosch-type relay. Use the #30 (common) terminal to go to the lights. Use the #87 (normally open) terminal to supply +12V to the lights from the same fuse the fog lights use. Use the #87a terminal (normally closed) to bring in power (through a resistor) for the DRL circuit. Hook your existing fog light wire from the switch to either the #85 or #86 terminal (let's use the #85 to keep this simple). Connect the remaining terminal (let's say #86) to ground. You should be able to connect the existing fog light wire from the switch to both the # 87 and #85 terminal. It will then trigger the relay and also provide power to the fog lights.

When the switch is off, the fog lights will be powered by the DRL circuit you create through the normally closed points in the relay. When the switch is on, the fog lights will be powered by the normal fog light circuit through the normally open (now closed) points in the relay.

The relay will close when you turn on the original fog light switch because that wire now causes the points to close and activate the relay.

You can try to use a resistor from a 2001 or older truck. They are located behind the driver's side headlight on the back side of the radiator support. It is a black metal box with holes in it. I suspect that the fog lights will draw less current, so they will be pretty dim using this resistor. You may have to experiment to find the right resistors. The stock low beams run at about 80% voltage while in DRL mode, so that is your standard. V=IR Where V=Voltage in volts, I=Current in ampheres, and R=Resistance in ohms.

Thanks for the info.
I will probably go with the resistor behind the driver side headlight.

I will look for power wire coming out of resistor and splice into it?
Run the splice into power wire to Fog light?
Disconnect original power wire from fog light that intailly powered fog light?

By doing above I will now have power to fog lights all the time while ingintion is on at about 80% of power to fog's.

If I use the 9500 high beam bulbs then I will have almost bright lights at fog lights?

Can I do above without running into issues of overheating wires/plugs etc. with the fog lights on all the time as driving lights.

 

You will have to experiment to prove out your idea. I would suggest using a whole new source of power and wiring for your fog/DRL system, and use at least 14 gauge wire. The more powerful bulbs may be too hot in your fog light housings, but you will have to test that to be sure.

If you don't have DRL now, I doubt you will have a resistor installed on your truck. If you do, and you have the DRL system that runs the low beams at 80%, then you should be able to feed your fog lights from the output wire of that resistor. With the bigger bulbs, the resistor should be closer to what you need.

Good luck, and report back with your results!

Thanks for the reply.

2002 and up had DRL?
I haven't had a chance to see if I have the resistor on driver side.
Since it's a 2001 there is a chance I don't have.
I probably have to get a power source that shuts off with ignition.
Any suggetions on a power source.
Any suggetions on a fuse/something in line to protect melt down?

 

Tap into one of the fuses in the fuse box next to your left knee. Fuses #24, 26, 27, 28 are hot in run. Check your owner's manual to see which one seems best. Don't overload the circuit. The fog lights don't draw much amperage, but your more powerful bulb option may need larger wires and fuse. You can research the current draw of the bulbs you are using by asking at the auto parts store. They should have a list of voltage and amperage ratings for each bulb number.

 

Thanks,
