Sooo, I don't know if this worked when I got the car or if it's something I've done, but: I have no interior lights whatsoever (ONLY passenger rear reading light). No boot lights. No puddle lights.
Traced wiring diagrams and Pin 20 on the CCM feeds the lot. There is 12v on Pin 20. Feeding boot light with 12v lights it up and it goes off with the latch. Does not light interior lights. Feeding interior lights (at either the drivers door or the harness on the A pillar) will illuminate interior lights but no boot lights.
Picture attached. Can someone help?
