I just finished installing my D2s today and the FlashCal does work to let you run fogs and high beams at the same time. See picture below. I also ran them through the factory fog light switch with a relay. I tapped into the wires at the TIPM instead of down by the lights themselves. Each fog light has it's own wire. Used a mini-torch soldering iron and sealed with heat shrink. I can give more details if anyone needs help locating wires. I ended up cutting a lot of the wires out of the Rigid harness that comes with the lights. Red and black with ring terminals to the battery, blue wire to one of the two fog light wires coming out of the TIPM (they both have be cut, so I just sealed up the other one) and red from the relay to both fog light wires (white/orange & white/yellow) going to the fog light connectors. I cut out the rest of the ground wires since the fogs and factory switch still use the factory harness ground.
