Just fitted some to mine that look the same . The controller had 4 wires . fused red - to + on battery , black to ground or (-) on battery . orange ACC wire (this turns drls on with ignition) which should go to a piggyback fuse as in preee's guide and a white wire which taps into sidelight to dim the DRL's when you switch your lights on.
If there like mine its worth checking the seal is ok on the alloy part of the DRL , I noticed the front lens on mine wasn't quite sealed to the alloy part so its worth bunging abit of extra silicone sealant on.
Pleased with how its turned out :)
