Well, after 3 days of
, brainstorming, troubleshooting, and many pages of this stuff...
-I am finally happy with the DRL/Independent Fog MODS. They are now talking to each other nicely, and working
the way they should.
Here's what the final project does:
** DRL's are controlled by the factory switch. They
turn off with the switch, and DRL's are on with the parking lights
AND the headlights.
** Foglights can be turned on at any time, as long as the ignition is on.
** Whenever the foglights are on, the DRL's are
automatically turned off. (Because I don't like the way it looks with both on at the same time...)
** Turn signals work the way they should.
I don't think I am going to post a full writeup on this MOD, because I'm not sure anyone is crazy enough, or cares enough to do it.
If you do plan on doing this, you need to complete the
Independent Fog MOD first.
I
had to do it because after several failed attempts to make all of the above conditions work, I felt defeated. No way Mr 4Runner(NM156) was winning this one.
Basically, the DRL's are turned on by grounding this green wire.
The factory wiring provides this ground when the switch is set to "DRL", or "Parking Light" only. If you ground the green wire with a jumper, the DRL's can't be turned off with the factory switch. I got around that by only applying an extra ground (via relay) when the taillights are on(meaning the head, and or parking lights are on). To make the DRL's turn off when the fogs are on, the entire circuit is cut (again via relay). This same circuit is normally closed (via, um...relay) to allow the DRL's to function when the switch is set to "DRL". Now you know why it took me a few days. Yes, it is confusing!
To make all this stuff work (at once) requires 3 separate relays, 13(!) different connections, and alot of patience to make the wiring look neat and clean. But, it's done. It works perfectly, and I win...
That said...
I
am planning on drawing up a wiring diagram(no way you can figure out the one above- it's written in
Antman 
) and posting it soon. I'll snap a few pics of the area where the relays are mounted up as well.
I'm a geek, I know.
Happy Modding guys!
EDIT- Wiring diagram here, and a few posts down as well...
antman, you are awesome. save all of us the headache of going through the wire diagrams piecing it together. i work at lexus, fully capable of figuring it out and have access to all the wiring diagrams but you break everything down well and save us the trouble. very much appreciate what you do.
