Rear AC vents part kit from 2022 Civic

[acurax]

So, if you just wanted to make a harness to integrate the Honda OEM USB-C module it wouldn't require as much and you would use the existing harness for the rear center console the keyless entry module.

To tie into the front USB-C you'll need these connectors and each will be split off to the original front USB-C connection and the rear USB-C connection.
- JAE MX34003PF1 (Gray, 3 POS, Pin Side Cable)
- JAE M34P75C4F2 (Pin Contact MX34)
- JAE MX34003SF1 (Gray, 3 POS, Socket Side Cable)
- JAE M34S75C4F1 (Socket Contact MX34)

The rear USB-C connector is:
- JAE MX34005SF1 (Gray, 5 POS, Socket Side Cable)
- JAE M34S75C4F1 (Socket Contact MX34)

Here's the connector layout:

To get the illumination working with the dimming, the closest connection to tap into is the parking brake/brake hold connection. The connectors to use so you don't need to splice into the factory harness are:
- JAE MX34012PF1 (Gray, 12 POS, Pin Side Cable)
- JAE M34P75C4F2 (Pin Contact MX34)
- JAE MX34012SF1 (Gray, 12 POS, Socket Side Cable)
- JAE M34S75C4F1 (Socket Contact MX34)

Here's the pin side connector layout [Made a correction, had 3 & 7 swapped]:

Wires 3 (white) & 7 (green) will be split between the parking brake/brake hold and the rear USB-C ports. All wires will go from the Pin Side (MX34012PF1) to the same location in the Socket Side (MX34012SF1) and then wires that split off of the 3 (green) and 7 (white) will go to positions 4 & 5 respectively for the USB-C 5P connector.

Also, I was able to buy just the splitter for $70 from mikstoreph by reaching out to them on facebook. All of the other parts for the rear vents w/ USB I obtained through Honda/Acura, either JDM Yamato or US based dealership's online.

What did you end up using for the under console ducts if you didn't get from the kit. I noticed that these ones on Yamato look like they might work since they go off to the right hand side of the console instead of the left (Items 28 and 30 for a 2023 Type R)

Those are what I used, though the first section did push against the passenger side center console trim panel. Also, where they connect together it shows a plastic clip, but that mounts the first section to the rear of the shift lever floor mount, which I did not get since I'm unsure if it would prevent the duct from being pushed in by the center console passenger side trim panel.

For anyone that's wondering, you're only tapping into the parking brake/brake hold connector for the lighting system connection. So everything is just passing through except those two wires which you are split to also be directed to the rear USB ports. I didn't want to splice into the factory harness which is why I went the route of building my own adapter harness, but to each their own.

These wires all tie back to junctions like this:

Which is located somewhere on the dash harness in this region. I think they are inside of the plastic piece I boxed in red. I think we can agree running dedicated wires to that might be too much of a hassle.

0.

Gotcha. I'm curious if it would even fit or work since it's for a rhd car. I'm planning on going this route but I have a hybrid racing shifter so maybe there will a little more clearance
I have a suspicion it also has the splitter but I haven't been able to track down a parts diagram for the air box on a JDM civic to confirm

Also putting together an order for the harness. I appreciate the research you did on all the part numbers.

What I ran into with the splitter is that unless you purchase the whole heater sub-assembly you can't get it. That said, I found that the Acura ADX has a splitter (79106-3Y0-H51) which looks very much like the one I got from mikstoreph.

Just placed the order for the dual type-c variant. Are there any read-to-purchase/ship options for 2025 DE5? Maybe a splitter of some sort that allow us to split the power supply from the front usb ports.

I'd be hesitant to steal power from the front USB ports or cigarette lighter. My understanding is they used to that and then switched to the connector in your picture which plugs into the fusebox. Do you have anything against using that one?

Not really, just that i don't know where the fuse box is. Us it in the cabin or engine bay?

Here's a DIY video I made when I installed the HomeLink MIrror. If you watch from 5:18 to 7:05, you'll see how to get access to the fusebox and which plug to use. They both connect to the same spot so when later installed my USB ports I had to plug into a passthrough connector that came with the harness on the HomeLink mirror. If you don't have a HomeLink mirror then you have nothing to worry about here and can just the spot on the fusebox.

For your case, you shouldn't need to remove that triangular side panel or the one above the fusebox (that was only for routing a wire up the A-pillar) but you can screw the ground connection under that second panel like I did in the video. You'll just have to get under there and route the harness under the steering wheel and zip tie it along some other wires, making sure you don't get in the way of the pedals, knee airbag, or steering column.

Though, if you want to ground to a factory ground there is one behind the the side panel which was close enough for me to ground my homelink mirror to and likely the same would be true for your USB ground.

Thanks for the suggestions! Will report back once all parts arrive
