Increasing head lights output (full LED setup)

[pb2k]

My Experience for anyone else looking to make this mod:

After pouring over the diagrams for several hours, and tearing half my dash apart, I found that the wires for the parking lamps and side marker lamps show up in a connector in the engine fuse box (along with the turn signals). If you want to isolate just the parking lamps it would have to be done here, but I was OK with running the marker lights too.

The parking lights and side markers are then tied together and then pop out at the main fuse block under the steering wheel on connector 4B pin 33 (pink wire fourth from bottom right). I grabbed power from the 10A GUAGE circuit on 4B pin 19 (green wire top right) by splicing in with an insulation displacement ("easy splice") connector.

I chose to cut the pink wire to prevent backfeeding voltage to the tail lights, but by doing this I lose the ability to use my front parking lights unless the ignition is in the run position. A multi-way switch could probably be added to fix this issue.


It should be possible to splice the cut pink wire directly to the green wire, however I spliced in a fuse holder with a 5A fuse(just the size I happened to have), just as a final safety measure.

Notes:
07' Hatchback 2 door CE.
0.7W LEDs in side markers (warning, larger COB LEDs won't fit)
~0.8W LEDs in parking lights (I'm looking for some slightly brighter ones)

Warnings:
The wires in the under dash fuse panel are barely accessible, you'll need small-ish hands to even get in there and if you break a wire or screw anything else up, it will be nearly impossible to fix without major dash disassembly.
