Does any one know how to add day-time running light in 01 QX4?

How much would be the cost?

I know on some honda's models, I can just a buy a little module that looks like a relay and just plug it in the box next to the fuse box near the left foot. Sometime I can get a used module very cheap from the junk yard.

Thanks.

The simplest way would be to add a relay in parallel with the light switch hooked up to the auxillary off your ignition. All you need is the wiring diagram. Oh, and make sure you use a high amperage rating relay (30 amp should do, since the switch probably just runs another relay).

Thanks, denisb. That's a great idea!

Maybe I can just connect the Accessories line (or EngineOn line) at the steering colum to the LightOn line from the light switch. The LightOn line is probably just to trigger a relay somewhere. Do you think I need two diodes to prevent electrical current from flowing back into the LightOn line or Accessories/CarOn line if one line or both are ON?

I really want to do this. However, I am still kinda afraid of frying the electrical system. My car comes with HID Xenon lights.

You shouldn't need to add diodes if you do it the following way.

1. Tie one side of your relay coil to an auxiliary line (key on line) and tie the other side to a ground.

You might be able to find a unused fuse port on your fuse panel (a little easier if you can). To do this, using a meter, connect one wire of the meter to a known ground (my suggestion is the outer ring of your lighter plug) and turn your ignition on and off until you find one that works with your ignition. If you find a unused one you can plug a spade connector in where the fuse leg would slide in. ****remeber that this means this line is unfused and a fuse should be added (10 amps should be sufficient).

2. Tie in the relay's Common (C) to the power going to the light switch and the Normaly Open (NO) side off the relay to the line going to the headlights. Basically, the relay's Normaly open side is connected in parallel to the light switch.

Depending on your electrical knowledge this might or might not be enough for you to figure it out. It's kinda hard to explain in words, I'm more of a hands on type. :frown:

If you happen to know where you can get a wiring diagram for the headlight wiring and fuse panel layout for an 01 QX4/Pathfinder :banghead: . I will gladly try to give you an exact wire/wire color connection diagram.

Looks like I just got a wiring diagram from one of my friends at NPORA. Let me take a look at it and I'll let you know how I make out. It's for a 2000, but it might be the same. The wiring diagram I have is also for a Pathy with daytime running lights already on.

Does yours have DRL and they don't work or does it not have DRL and you would like to have them? This will make a difference on how to wire it.

Get a hold of the Canadian version of your year, since all vehicles in Canada run daylight systems, they power the same bulbs but at a reduced voltage
