When it comes to this stuff I'm pretty decent, but looking at the above picture with the two jumps, and then looking at Verblatts picture with all 5 jumps.? As it relates to the fogs, when you compare the one with the two and the one with the 5, they are doing the same thing, there is only one relay on the 07 model for the head lights, hi/low, which is being utilized in the above picture so that when either the lows or highs are on the fogs come on, and in the older model there are two relays that need to be jumped to accomplish the same function.? So this doesn't seem to work on the 07.? I just tried it by adding a third jump, connecting to the lower left post of the hi/low relay and the only thing I got it to do was have the fog lights on when the car was off.
Am I doing something wrong?
Nope, just you don't need as many jumps on the 2007/8s as the 2002/6s did. The 2007/8s already basically come with the "All-4-on-High" Mod from the factory. Thus, whenever you turn on the high beams, the low beams are also on. So you don't need Vertabatts Diode #2.
So, basically, what we are doing is using the low beam to power the fog lights. His Diode #5. But because on the 2007/8s the low beams also come on with the high beams, you get FT Fogs with both High and Low beam headlights. That's why you don't need Vertabatts Diode #1.
Then, following my instructions above for FT DRL, you are powering the DRLs from your low beam switch. That is, whenever you turn on your low beam (via the relay), you also turn on the DRLS. Now, because the DRLs don't have a relay, you have to run more power to them because you're actually using that power to run the lights, not just switch the relay. That's why we use a bigger diode than Vertabatts Diodes # 3 & 4.
Let's talk about what a relay is. A relay is just an electrically activated on/off switch. Think like the light switch in your room being turned on via an electric switch. By doing it this way, you don't need as much amperage to turn on the switch since all your doing is turning on the switch, not actually powering the light itself. (Tech guys, don't kill me here - I'm just trying to lay it out in layman's terms.) Anyways, you can use 0.1 Amps to turn on the relay that then powers the on/off switch that now sends 10.0 Amps to the lights.
So, you need only 1 small diode from the 3114 relay to turn on the 9831 relay to turn on your fog lights whenever your headlights are on (Vertabatts #5). Then we need the larger diode to run power from the same 3114 relay power source directly into the DRLs since you are running those lights directly and not via a relay.
BTW, I have really got to hand it to Vertabatt! He did a great job on his original write up. I wouldn't have figured out the 2007s without his original instructions. I just took his instructions and then saw where the 2007/8s had changed and applied it from there. Took me less than an hour to do - and that included allot of experimenting to make sure I got it right. (If you look in the pic, there's actually a little burn mark near that white chalk mark where I got it wrong.)
