Got this new mod idea... but don't know how to execute it.
Hey guys,
Last week when I was installing some new interior LEDs, I realized our map lights don't light up when the doors are open like many new cars nowadays do (say, the 3G TL). While my 9LED festoon dome light is quite bright as it is, it would be pretty sweet to get the map lights to turn on too. I am not too familiar with all the wiring and stuff, so I was wondering if any of you gurus can clearify/help me out with this.
Thanks!

I think I've ask the dealer the same question about this mod before and they said something about the wiring for the power will need to be swapped out completely because the voltage or wattage the wiring can handle is precisely measured... Anyway... hopefully we can get a anser from alleyesonmeee's dad... It should be a great mod...

is simple
if the map light is negative trip than hook up blackwhite to the ground side of the map light
if is possitive trip hook up a relay to swich polarity from the blackwhite wire to the positive wire on the map light

easy!
but you cant just connect the wire from the dome light to the map lights, cuz then when you would turn on your dome light (using the ceiling switch) your map lights would light up too.. You will have to use a relay to make sure the current goes through only when doors are open (door signal will trigger relay's coil to let current from the dome light go through).
If someone could provide me with the wiring diagram for the dome, map and door lights i would draw a wiring schematic.

Good mod idea. I'll have to check my Helms electrical schematics manual.
ill be waiting out for that. im a total n00b when it comes to electrical stuff.

This is the best solution, and simple as well. The problem is finding the wiring diagrams. Someone with a helms manual could easily tell you were to find all the wires and the colors.

Revivial alert
alright so I realized that the LED's i bought for my map lights rarely get used and I was thinking it would be really cool to have them wired up to the dome lights so they go on when the doors are opened. So i searched and came accross this thread and another (https://acurazine.com/forums/showthr...8#post11428348) talking about the same idea. so i'm wondering if 2 years later this idea has been carried out.

its a red/blk wire that gets its power from the taillight relay. one u turn on the parkin lights it powers the glove box and 2 vanity mirrors. if u get 2 t-taps and some wire im sure u can just take the red/blk wire and wire it up to an ignition sense (+) wire. then the 2 vanity lights and glove box will be on as long as the key is in the on position.

i forgot to add that once u tap into that red/blk wire itll also send power for all the switches and the gauges to turn the illumination on. so basically you could cut the red and black wire at each vanity light you can just send the vanity lights power from the ignition.

ok so from what i see in the schematic theres a white/blue wire that powers the dome light when u open the door. if you tap into that wire and run it to the white/blue wire for the map lights it should turn both lights on when u open the door. the only down side is that it wont dim slowly like the dome light does because that works off the ground side.

did this in my car about a month ago. looks great and dims, just like the dome light.. tapped the dome light ground and used the constant power from the homelink.. BUT the problem is, unless you rewire the homelink or run your own dedicated constant power, it will only work with the door open. because the lights and homelink share a common ground.

So your map light don't have the normal functions, they only come on with the dome?
