Hi all, just finished this update on my 2006 Legacy 3.0R (European version).
I wanted to share some experiences:
- In my car the wire I had to tap was a black with a red stripe one.
- I experienced soldering directly onto the switches is the easiest way and doesn't require any baking which can melt the switch. See attachment.
- I tapped the wire near the front seats instead of at the dome light. This reduced cable length a bit.
- Added a car connector to the wire so the map light unit is easy to detach.
- Replaced all interior lights with LED ones.
Thanks for the original post!!
