Yup -

Rear Cover - 83451T20A41ZA

USB Ports - 8A350T20A01

Harness - 32114T20A10

As far as modifications go, you’re essentially cutting off the end connector that supposed to go to a port in the automatic shifter area on base civics. We’re extending the wire to go the cigarette lighter harness to get the 12V need. The USB Port converts the 12V to 5A used for our mobile devices so there no concern of damaging ports on phones/tablets.

if you need pictures, I’ll take some and post them up here.
Pics would be awesome! Thanks!

Apologies for the delay, picture and quick explanation below:

Below is the 12V/Cig liter connector

The harness you get from Honda is short and the connector doesn't work with the FL5, so you'll need to cut the unusable connector off and lengthen the harness to reach the Cig lighter wires.

When you cut off the unusable end, it’ll leave you with 5 wires. You’ll need to combine 3 of the 5 for power and the two for ground. Grey, Orange and Brown are Positive, Black and Blue are Ground.

Once you have them combined, lengthen both wires and tap into the positive and ground wires for the 12V/Cig Ligher (Black is ground, White is positive). I used electrical tape and some lom and ran the wire to through the shifter assembly to the back. I zipped tied it to existing wire while running it through some it’s not laying around loose.

Run to the end and plug into the USB hub and snap everything back together.

Thanks for sharing the parts and photos.

Any idea if USB-C ports part exists? I tried to search, but looks like only USB-A ports part is available.

I know the MikStore has a USB C option, but I don't think the same harness will work. Whereas Mikstore will give you a "T" adapter that goes into the Cig light for the USB A ports, the wiring is apparently different for USB C ports.

EDIT: Link for the Mikstore

It's weird, because they don't offer harness for USB-C Honda Original.

Seems like what I need:
1. Rear cover from any Honda dealer shop - 83451T20A41ZA.
2. USC-C + USB-C Harness from Mikstore.

My car is ITS DE5. Seem like Integra A-spec with tech package comes with USB-C:
(scroll to 6:35)

This is the OEM USB-C:

This is the EOM harness:

This is the EOM panel:
https://acura.oempartsonline.com/oem-parts/acura-rear-cover-83451t20a41za

It might fit CTR also, but can't tell for sure.

I didn't find instructions or video of how/where to connect the harness. I will keep looking and probably will call a dealer.

The connector looks similar to the one I picked up for the Civic. It seems like the if the front connector doesn't exist, you'll need to extend the wire and tap into the 12V connector like I did.

You are probably right. I asked one of the guys I know from a nearby dealer to get me a list of parts used in the Integra A-spec with tech package. If he can get the list, it will be ideal.
