DRL & Fog Light Mod Done!

[Mike07SE]

Well yesterday I tackled two mods on the 4Runner. After I had got done doing an oil change I decided to follow J.A.'s writeup on how to perform the foglight mod with a slight twist. I was looking to get the ability to run my foglights while I have my parking lights on, but didn't like how his mod basically has the fogs on whenever the car is on (therefore I would have to remember to turn the fogs off during the day). I decided to remove my battery and splice into the power wire for the left side headlight marker light and run the wire up to the fog relay like he has in his writeup. Works great! Now they're off when the main light switch is off and on when the park lights are selected.

After I got that all buttoned up, I decided to head down to the dealer and get my DRL's turned off (can't stand them, personal pref.). Armed with the TSB on how to turn them off with the scanner, got that finally taken care of. That ended up costing me about $40 for like not even 10 min in the shop :bugeye:! But the way I saw it, the non DRL relay would've cost nearly as much, and I wanted to have the option of adding an LED signal relay down the road and not chance having things not work right when I do.

Hey, congrats on the mods.

But to clarify for others...my fog mod does NOT cause the "fogs to be on whenever the car is on ". It allows the factory fog switch to turn the fogs on (and off) independent of the parking/headlamps, whenever the vehicle is on.

It looks like what you wanted to do was to keep the fog switch on permenantly but have the fogs come on when the parking light are switched on and shut down when the parking lights are switched off, was that the intended result?

Thanks for the clarification, but yes, that was the result that I was looking to achieve.

Also, thanks again for your writeup. Just by your being able to point out the pin on the fog relay as the current sensing pin I was able to figure "hey, all I need is to find a marker light" to get switched power from to give me the results I wanted.
