03 DRL to foglamp conversion - Click HERE for Original Thread

Okay. Yes, I know this topic has been discussed and yes, I have searched through previous threads and found them to be very informative; however, I do not have a ring on my pinky nor am I so inclined to splicing wires erroneously in my 03 X.

My question is this. Is there a definitive step-by-step for converting the Canadian model DRLs to run (and satisfy the following criteria):

1. the foglamps at full intensity when the engine is started?
2. leave the foglamps burning while the high-beams are on?
3. disable the half-intensity higbeam DRLs?
4. leave the functionality of the foglamp switch when either the low- or high-beams are manually activated?

The request is probably too hefty but any help would be appreciated (as I pull out my hair deciphering the schematics). ;) I apologize in advance if in fact something that matches the above has been posted as I will attribute my oversight to far too many hours perusing the previous threads.

Since we don't know of anyone who has done this, all replies, ncluding mine, is pure conjecture. Notwithstanding, you may have read my previous posts long ago and concluded that I do have all the conditions you noted, sans the OEM DRL function as I have a US '01. I cannot give you blow-by-blow instructions (I doubt anyone has done this on a Canadian model either) but hope to offer some paths for thinking.

Because I know for certain that color codes have changed over the model years, focus more on the pos/grnd and function descriptions of the wires rather than relying on any color codes I provide. I am using the '01 Canadian diagram for referencing.

1. the foglamps at full intensity when the engine is started?

Easy one, especially if you want them on whenever the engine is on, regardless of whether it is daylight or night-time. Connect a same-gauge runner between the Yellow IG2 wire to the very thick wht/red (20A) main supply wire which leads from the combo switch to the Fog switch. Whenever ignition is on, fog light switch and relay gets power.

2. leave the foglamps burning while the high-beams are on?

Bypass the fog cut-out at the combo switch harness by shorting the main ground (thick Black, either or any, all conjoined) to the ground of the fog light switch and fog light relay, mine is wht/blu. The wires are right next to each other on the combo sw harness; confirm wire function with your schematic. The idea is that the fog light relay and fog light switch negative wires (conjoined at some point) is always grounded, so they will function regardless of high/lo beam position.

3. disable the half-intensity higbeam DRLs?

This is uncharted territory. The DRL module doesn't simply control the DRL function of the highbeams. It is an integrated circuit that powers and controls all headlight functions, and interfaces with the driver's multiplex cotntrol unit. Haven't done this before, but this is what I would do. Provide unfettered power highbeams by shorting red/wht to red/yel and red/grn to red/orn (left and right), just like the US models, compare US/Canadian diagrams to see what I mean. To prevent the high beams from being cut out and controlled by the DRL module, cut seal off the blu/grn at the DRL harness (either blu/grn won't matter, but aim for the one that leads to the high beam cut relay), this prevents the highbeam cut-in relay from gettting connected to ground and closing the circuit. This does not interfere with normal high-beam operation, only cuts the DRL access to the high beam cut-out, if you do the following; Bypass the high beam cut relay by connecting ORN to orn/wht at the relay. High beams will now be completely independent and unaffected by the DRL module.

4. leave the functionality of the foglamp switch when either the low- or high-beams are manually activated?
Same as #2.

To clarify, did you want the fogs to stay on, even at night?

When interpreting confusing schematics, I usually find it useful to draw into the diagram the direction of electron flow, from positive power supply to its destination at ground, allowing me to trace a path and understand which device is controlled by voltage gates, and which are controlled by ground switches, and what other components my actions would affect. This might help to avoid shorting-out an expensive component like the multiplex or main computer. I have a fax machine and am willing to look over your manual diagrams if you PM me.

Good luck.

Bruce,

Thanks for your comprehensive reply. Unbeknownst to me prior to your reply, I only had two criteria to meet and your solution satisfies all.

Points 1 and 2 seem simple enough and I will tackle them this weekend if I can find time. Point 3, like you've mentioned is unchartered and I do not wish to pursue it at this time... I suppose that I can run with the half intensity DRLs in conjunction with the fog lamps. I guess item 4 is moot in light of your wiring suggestion in item 2.

Thanks again... I appreciate it!

David
