Footwell Lighting with Exterior Lights QUERY

Hi all,

I have the lighting package on my 3 and like the way the footwell lights light up; I would like them to be on when city lights or headlights are switched on during night driving.

Is this a possibility?

Thinking of how the lighting and electronics are all put together and made to work with preprogramming of the stock components, it should be a possibility to code or hack the car's system to make this work, no?

Has anyone tried or done this?

I would love to know and would love to make this happen. Those Lexus' are almost making me jealous!

Sounds like OP would like to use his footwell lighting as ambient lighting. I'd be curious too if this was possible via coding.

You can replace stock footwell lights with F-series lights that have white/amber mood lighting leds (63319242161) and connect amber or white leds to pin 48 in X14261 FRM socket to have them light up together with your lights.

You'll also need new 4-pin sockets and pins (61132359994) to use with the new lights. Plain wiring job, no coding required. Did this in my E87, too lazy to do it again in E92, although I expect the mod to be more rewarding with tan interior the E92 has.

Question: Does pin 48 have a previous connection or does it simply have vacancy for pinning?

Additionally, can existing ambient lighting be used if the F-series lights are not?

Thanks a lot for your input. It's great to know of contribution from those of us who've paved ways.

Happy to help

It depends on the model/options I guess.

The 48 pin socket was vacant in the E87, but the car was pretty stock without the lighting package at all. Haven't checked in the E92 yet, but I wouldn't be surprised if it is used for something like ambient light strips in door cards/rear panels.

I'm not sure I understand your second question though. These new modules are direct replacement for your old footwell lights - they are the same size and fit the same openings in footwell panels.

The new modules have three leds: brighter white for illuminating footwells when the doors are opened/overhead light is switched on and two dimmer leds, white and amber, for ambient lighting.

It was years ago, but if I remember the pinout correctly, old positive and negative wires for brighter illumination connect to pins 1 and 4, and pin 2/3 connects to pin 48, depending on your ambient lighting color choice.

On a second thought, it should be possible to splice the ambient lighting wire into any backlight wire. The cig lighter or center console storage backlight for cars with no cig lighter may be an option.

Although connecting to FRM feels cleaner to me.

Nice!

I'll try to look into this sometime. I'll report back what I find.
