Hi, mine is wired from the fuse box with a piggy back fuse connector. This runs a wire through dash board into engine bay to the genlabs drlr2 relay, which is behind my headlight. From memory this runs positive and negative to both sides of the car. I then connected the 3 led's on each side together with butt connectors which plug into the wires from drlr2. One wire from drlr2 cuts into side light or dipped beam whichever you choose so that the led dims with the chosen light. I put mine into side light so it dips with them incase ever parked at night. One other wire goes to earth point on bodywork.
Led's go on and off with ignition.
I'm sure there are instructions somewhere on this forum if you search drl's. You will definitely get them with the drlr2 relay which is what controls everything and allows the lights to dip to make them legal at night. Drlr2 had 5 wires I think. Power from ignition, earth, positive and negative to led and sidelight connection.
Depending on which Drlr you get some go on and off with indicators etc so may have additional wires.
All this is from memory and I did it a couple of years ago. Hopefully it will
help. I Can dig out instructions if need be.
Last I heard is genlabs went out of business, but if you pm Robthebubble on here, he is the light guru. He makes the relays so will supply you one with instructions for wiring.
