My wife requested that I put in footwell illumination lights into her Fit like I have done with my other cars, so I decided to also try out the ambient light kit…..well I didn’t like where the instructions told me to place them since the drivers seemed too far into the footwell, while the passengers would be further out and most likely visible. The color of the light modules are also more of a dark teal than 470nm wavelength blue, so I modified and also put some lights in the gloveboxes.
Well it came out better than I expected so I thought I'd share:
Footwell Illumination (door open/unlock)
Ambient Lights (parking lights or headlight switch on)
Ambient Lights (parking lights or headlight switch on) + upper glovebox open
Ambient Lights (parking lights or headlight switch on) + lower glovebox open
Ambient Lights (parking lights or headlight switch on) + both gloveboxes open
Since I didn’t like the light module placement and color of the ambient light kit, I used flux leds dimmed with 5.6kΩ resistors mounted inside the recessed area instead so that they’re completely hidden from view and angled better.

Also reused one of the light modules from the kit as the lower center cup holder area light.

The glovebox lights are also wired to the parking lights
The switch was cut and bypassed for now so that the ambient lights & glovebox are always on with parking lights. I figured that if the blue bothers me enough I can use a switched audio potentiometer to turnoff and dim the ambient lights.
Cut and bypassed switch connector
The switch itself was rewired to the footwell illumination with a diode. This enables the driver to turn on the footwell lights without turning on the domelight. This is for times when you need to look for stuff on the floor but can’t/don’t want to open a door, similar to the domelight switch:
Dash Switch OFF = footwell & domelight ON only with door(s) open
Dash Switch ON = footwell ON, domelight remains OFF

Here’s the original ambient light kit harness

Added footwell illumination wires
G5/G7 are the pink(+12V) and blue(GND) pins on the dome light connector in the fuse box that comes from the MICU marked below. So the footwell lights will fade out and come on just like the domelights with unlocking/locking from the keyfob and opening/closing doors.
