Hey all,

I have a 03 Canadian SD with no fog lights and therefore no fog light switch.

Well I bought a used set and am wondering how Im going to get them working. I've checked and the fog wiring harnesses are in the bumper (as I expected they would be), but there is no switch on the turn signal arm.

I don't want to install a switch, what I'd rather do is just hardwire them to always be on. I imagine this should be similar to the standard fog light mod, but I need some help to figure it out.

Has anyone done this mod? Does anyone have the wiring diagrams for the IS300 lighting?

Thanks for any help.

 

The relay for the fog lights is in the passenger side kickpanel. Backside.

You'll do the same mod as the "fog light mod"

However, you'll have to add one more thing.
Pin # 3 (top pin on the relay) will have to go to a power source that is constant.
Run that pin to the battery with an inline 15 amp fuse.

This is how the relay looks.

---- Pin 3
---- Pin 5

Pin 1 Pin 2

 

On a pervious auto, I wired the relay it to a "switched" (ignition on/off) hot lead. This way the lamps turn off with the key...in case you leave them switched on in the rain or snow.
