In all honesty in haven't a clue how its done, my brother did it as I use the van for work, he uses it as a night time project after his work haha.
Ill try and explain the bits I remember. The significance seems to be in a 5 pin relay that switched the circuit when you go from no lights to lights on, so they are tapped into the earth side of the indicators as that's how to vans original indicator relay works. There is a permanent live feed to LEDs, thus, the relay actually switches them off. When the lights are switched on the relay switches and the live feed powers the lights on but when the indicator is pressed the 5 pin relay switches the live feed off, in the same way the vans original indicators work.
Some more technical minded people might find a flaw in that as I didn't get all the details I just let him do it. It can't be a major job for a compitant person a it took him just a few hours to change from marker lights to lights and indicators, that included adding in the relays(1 used for either side) and running new 2 core cable from rear marker lights.
Ill try and get more details when I see him again, they don't work on the hazards yet, he is yet to troubleshoot a way to do that.
I don't switch my lights on... I turn the dark OFF!
