Wiring a new sidelight feed

[chriz1]

So I be done a retrofit to xenon on my e90 and all works but the passenger sidelights go off after
A minute Or so.. Must be a wire wrong somewhere but I've spent days checking it and can't see where I gone wrong as they go off to a ecu that controls the lights
So thinking of Just wiring a new 12v feed where's best place to pick it up from?
Thanks
Chris

Makes sense! But wouldn't the drivers side also so that maybe I house swap them to see if the drivers goes out then and passenger stays on the opposite to what is happening now
