Ok, so I've done this to the Forester as it should have been done by the factory.

Overview:
The whole point was to introduce more light into the cabin when the doors are opened. I wanted to retain full independent use to both Map Reading Lights when the doors were shut, and have them both come on when any door is open. This method also allows the Main Interior Light to be switched to the ON position at any stage without bring on either of the Map Reading Lights.

For the sole purpose of being lazy, I will refer Map Reading Lights to MRL and Main Interior Light to MIL

Also Note:
Plastic Trim's are easily scratched these days, if you only have a small flat head screwdriver, use an old ATM card or gym membership card to limit damage to your trim's

What You Need:

    Soldering Iron & Solder
    Electrical Tape
    3mm Wire Approx 1m Length, depending on if you have sunroof
    Small Flathead Screwdriver or Plastic Trim Removal Tool
    Old Plastic Card - ATM, Credit Card, Gym Membership, etc...
    Medium Size Phillips Head Screwdriver
    Small Needle or Spike ( to swap two wires in a plug connector )
    2 Small Diodes 3amp is plenty
    1 Hour

Step 1:
Using a small flathead screwdriver or plastic trim removal tool, carefully pry the clear plastic cover off the MIL
Image

Step 2:
Once removed, you will see TWO self tappers, remove both self tappers & place into cup holder, then carefully lower MIL down and disconnect wiring connector.
Image

Step 3:
Carefully solder a 3mm wire to the YELLOW wire ( 3rd from left ) on the switch side of the MIL, cut wire off at approx 50cm ( if you have sunroof allow more as the MIL will be further back )
Image

Step 4:
Now go to the front of the car, and open the smaller sunglass holder flap. This will reveal the first of 3 self tappers required to lower the centre roof console.
Image

Step 5:
Now using a small flathead screwdriver or plastic trim removal tool, carefully remove MRL Cover
Image

Step 6:
This will now reveal the two remaining self tapping screws that need to be removed in order to lower the whole MRL Console. Pull down at the front, then slide forward towards the windscreen to remove console without damaging the plastic locating tabs at the rear of the console
Image

Step 7:
Once the MRL Console is down, disconnect the two pin plug and take to your working bench.
Image

Step 8:
Using your spike/small needle, carefully open the back of the two pin connector plug by flicking the tabs out at either end. ( in the pic you will see the yellow and black wires, this is how they should end up in the plug... )

You will need to push the white locking tabs out of the way, then carefully pull the terminal out of its location and swap the two wires over
Image

Image

Once these two wires have been swapped over, you can push them back into the connector, and return the back of the two pin connector plug into its locking tabs & return to mounting base on MRL Console

YELLOW WIRE of MRL should connect to BLUE WIRE of HARNESS
BLACK WIRE of MRL should connect to BLACK WIRE of HARNESS

Step 9:
Info about diodes
Image

Now get your two diodes, solder the end without the band to each of the MRL switches, when looking at it from the top, the switch contact that is closest to you.
Image

Image

Step 10:
Now solder the wire from the MIL to the other end of each diode & tape up ( you will see how I've run my wires in the pic below
Image

Step 11:
Now plug the two pin connector of the MRL back in and test....

Step 12:
Now that everything is working, refit MRL Console back into roof cavity, and replace all three self tappers, refit MRL Globe Covers & close Sunglass Holder

Then refit MIL back into position with two self tappers, then replace Globe Cover and clip into place.

Step 13:
With door closed and lights all off, operate each MRL independently and check.

Will door closed and lights all off, then open any door and MRL's and MIL should illuminate.

Shut door, and after 35-40 seconds, all lights should extinguish

Step 14:
Pack up equipment and pat yourself on the back....

Great idea, thanks for sharing.
Speaking of diodes, what brand of replacement LEDS are you using in the pics?

I think that the SF requires a slightly different mod as the thread title is specific to SG9, Chris can confirm this.

Cheers

John

Carsubie, I'm just using replacement festoon LED's I bought off ebay, they do the job, but dont offer a huge amount of extra light.

I have a square LED panel which has two wires running out the side, which then adapts to a different number of fitments ready to go in, just been too lazy to do it.
