DTRL Wiring Help

[projectRDM]

The Canadian DRLs can't handle any higher wattage bulbs without melting the casing, so you're fine with just tying into the parking lamp circuit if that's all you're after. Otherwise, a switch through a relay off the ignition will keep them from staying on after you take the key out.

And fabbing a new casing is probably the only way to get them to handle more wattage...right?

While I tend to agree, I would want to err on the side of caution and say don't do this because there's no telling what kind of bulbs and what shape the parking light circuit is in.

I wired mine with 1 relay and a switch which means I have to remember to turn them off but it's not to hard being that I have HID's in there. Kinda hard to miss.

S-13's have wiring already in the harness for fog lights. There is a spot for a relay in the relaybox under the intake box, a connector for a factory switch under the dash on the driver's side, and a two pin connector by the battery (one orange wire, one black). All you need to make it work with the wiring that is already present is a blue relay, get the OE switch from the dealer (about $20), and make your own harness to go from the connector by the battery to the lights themselves. There are 2 problems though:
1: I may have gotten the last switch in the US when I wired up my silvia foglights like this as when I ordered it it was special order, but in-stock at the warehouse. When I called back because they were lagging the part was backordered acdcording to their computers. This problem can be resolved by simply using a toggle switch with the stock wiring, not really a big deal.
2:Using the stock wiring the lights will only come on when the headlights are on and will go off when you turn your brights on. If you have or are planning to upgrade to HID's it isn't much of a problem, but if you plan to run your stock bulbs or do an h4 conversion it may be a problem. I'm sure there is a way to bypass the auto off when the brights are on somehow, but it will take some staring at wiring diagrams.

I'm working on doing this on my 240. I got a JDM fog light switch that plugged into the empty harness plug under the dash...fit perfect and lights up as well.

Here is the back...it's the one on the right:

Here are the two fog light switches I have...the one on the left is broken, the one on the right is the one I used:

I have my CDRL's installed now I just need to order a fog light relay and run the wires from the plug near the battery box (which I haven't located...but I haven't looked very good yet). Anyone have a picture of where the plug is? Hopefully I'll be able to finish this in the next few weeks...soon as I do I'll post more.

I found the plug for the fog lights behind the battery...here is a picture:

I ordered my fog light relay last night and should get to the wiring soon after it arrives.

Got the fog light relay in yesterday.



Hopefully I'll get to the wiring this weekend .
