I just read through all 9 pages of this thread. I have learn a lot more than reading just the first 2 pages. (as one would expect).
Here is my takeaway. I know I should have read the whole thread before posting, but 9 Pages is alot, expecially when many of them are about how to purchase LEDs.
This mod was not posted in a Generation specific thread, yet everyone that posted has a Gen 4 or later. I am planing on performing this on my 2004 Wagon. People tend to fry their Integrated Units. However so. Best I can tell, the Jury is sure that it may or may not being 36 Total watts, as apposed to the 8 that it intended to have. Many thought that they could wrap the wire around the bulb as appose to soldering to the Bus bar down stream of the switch. That sounds very poor. Icy in Post 55 was the first to correctly think of de-pining the map lights plug and swapping the contacts instead of cutting the body side wires. Yamarocket630 in post 144 Was to to first that I could tell that stated the Subaru wiring diagram is wrong about the Map lights.
It would stand to reason that I or someone should update and upload the factory diagram for Gen3 and Gen4 map lights. This should help ease the mind and add clarification of those plan on performing this mod.
Also, Gen3 people. I think I have a more factory looking solution that I will post in a day or so. It takes advantage of the Gen3 (MY 2004 anyway) Different Fixture layout.
