Hey guys just wanted to make a post on the ambient dome light install, this install uses all oem parts.
my 2011 crz had this feature and wanted to add this to my si.
installed on a 2012 civic si.

NESSESARY TOOLS!
trim removal tool
phillips and flat screwdriver
soldering iron
tweeters
electrical tape
multimeter
plastic weld or super glue
wire strippers

NESSESARY OEM PARTS!
honda unit with the ambient light
misc honda interior connector
(can get from pick and pull yard or online)
I was fortunate to have all parts lying around,
light unit used for parts was from honda oddesy 2014ish year not sure,
dark grey wire pigtail that is used for the radio connectors.




First thing was to remove the dome light unit and disconnect the wires. Then take apart the both units with the buttons down to the circuit board (its pretty simple there just few clips on two of the sides).

NOTICE: careful when removing the buttons, the sun roof button just pulls off but the light switch has clips on the sides. Learned that the hard way broke both of them, luckily one just broke in half not at base and still can move switch just had to use a lot of glue to the circle base. Circled in red is what moves the switch. Circled in blue is where the extra glue was added to hold the switch in place. (only temp fix).

the one on the right is the si unit

next step is to solderer the led and the tiny resistor(steady hands and a fine soldering point helps)
note: that the led has a little notch on the edge side

Comparing the inside of the hole the parts unit has a light diffuser molded in, will be cutting that out and gluing it into the good unit.

Next step is to carefully drill out the hole using dermal tool with small drill bit.

Ambient center console light OEM! (part 2)

continuing...

Next step cut out the part that holds the plastic light diffuser.

Also I separated the clear plastic by grinding down the little bit of gray plastic melted on top holding it to remove to not scratch while trimming and gluing down the mount.

Test fit in the good unit

Used a razor to give a mechanical adhesion for the super glue, I usually don’t use super glue but the part is small and light should be enough to hold it.

Used a small drop on one of the legs to hold it and align it, then removed the clear plastic and added glue all around. Then left to dry.

Looks oem minus the little spot where the drill went little bit too far.

Next step is to get the pig tail to remove one of the wires. Use a small screwdriver to lift up the black piece on the back and you will have to de-pin one of the wires. After some testing, on the connector for the switches, if you look at the connector with the clip part facing you the wire with the green arrow is the power wire already there for you, all you need to do is add the ground, the wire you de-pinned from the parts connector will go in the last slot (blue arrow), the red wire in between is the ground for the connector, you will tap into the red wire (red arrow), and add your wire (blue arrow wire) to that red wire to ground the led you just added.
(connect blue arrow wire to red arrow wire)

Last step is to test, and then reassemble
Note: make sure to turn on the lights to city light or to full on to test, will not be lit in off position for lights.

Initially when testing it out the pink wire completed a circuit for the led but after tapping into it and fully installing, the led would not turn on, took a minute to figure out that I tested it, had the door open and had tapped into the door dimmer wire. Retested it and the red wire was it, so insulated the pink one and tapped into the red one.

Merged.

The three parts are not in order because during a merge, individual posts appear in the time-order in which they were originally posted.

And yes, there is a limit of 10 pictures for each post, but not thread.
