OEM HomeLink Mirror Retrofit (Confirmed Compatible)

[feldsam]

Hello everyone,

I can confirm that the OEM Honda Accord HomeLink mirror retrofit is fully compatible with the 2026 Honda Prelude.

Parts required:

• Automatic Day/Night Mirror Kit (P/N 08V03-3A0-100)
• Attachment Kit (P/N 08V03-30A-100)

The mirror kit is available here:

College Hills Honda – Day/Night HomeLink Mirror Kit

When ordering, make sure to also select "2023–2026 Accord Attachment Kit ($44.90)", as it is required for the Prelude as well. The mirror alone is not sufficient.

Accord installation manual:

2023–2026 Accord HomeLink Mirror Installation Instructions (PDF)

The installation is virtually identical to the Accord.

• Wiring harness is identical.
• Cable length is correct.
• The fuse specified in the Accord installation manual is correct.
• Mirror mounting and headliner disassembly are the same.

The only difference I found is Step 7:

• On the Accord, the left sun visor holder is released by pressing the locking tab with a small screwdriver.
• On the Prelude, it uses the traditional Honda quarter-turn retainer. Simply rotate the visor holder about 90° and pull it out.

No other modifications are required.

I so want to do this! Thanks.

But, I am hesitant to route the power wires and was hoping the auto dimmer power would be enough. Is it possible to use that power for the homelink power?

(Ah, the auto dimmer is only powered with the engine; the homelink needs power always)

(My current clip-on opener remote is the thing that rattles! I often put it in the glovebox on longer drives. )

Hi, auto-dimm power is only when “key” is in on position, so there is no power when car is turned off. Original auto-dimm mirror use different connector too. Yes, you can create own reduction if you buy/get somewhere proper connector, but I think, $45 for original attachment kit, which is plug and play is better idea.

Well done. I'm a modder as well but not on my wife's Prelude. The BRZ and Outbacks are mine to mod.

The Prelude does not have a HomeLink remote for garage door openers?

It does not.

 

[rexracer22]

It does not.

For its MSRP it should have Homelink, power seats, heated steering wheel, rear collision braking. I wonder if Honda will include some of these options in future models.

Homelink is a mixed bag. I have it on my Subies. On the 2022 Outback it works just fine. On my 2025 BRZ, not so much. I think it has to do with the per car licensing fees charged by Homelink, the compromises that it involves regarding security, and the headaches it causes the dealerships when Homelink doesn't pair (this is becoming more and more common). What I did to make everything work was to install a compatible three-channel receiver in parallel with the OEM door motor receiver, then use the remotes provided with the device to pair with Homelink. I can now use Homelink in both cars for open/close and home automation integration. I can set house mode to Home or Away and have the security and lighting system respond accordingly. This wasn't too difficult for me to do but I spent over 30 years in the residential system integration industry and (literally) helped write the book (ETA/TIA Standards) on structured media in residential applications. If I still had my business (I sold it and went on to teach Electronics Engineering Technology) I would tell a customer who was interested in Homelink integration that, unless done properly, it is a sucking chest wound in terms of security. And implementing it properly is a PITA.

Thank you for the awesome write-up!

Power seats are dead weight in a sports car.

Power seats are dead weight in a sports car.

As is the other requested feature - sunroof. The double-bubble roof is gorgeous and would be destroyed with glass.

I believe power seats and a sunroof add 2-4 inches to the car’s height (if the maximum passenger height is fixed).

Double-Bubble... I like that. I always called it a reverse Mohawk. My BRZ has it as well and it also has reversible head rests to clear a helmet. How cool is that?

Security is a huge issue. I always try programing my garage remotes to use two buttons instead of one to activate. Nothing happens when pressing one button. Thieves would have to know which two buttons to press to open the garage. I was able to do that with Lexus.

Thieves have found vulnerabilities in some BMWs and other brands where thieves hack into the keyless door locks. They hack and unlock the cars to gain entry into the cars. They look for garage door openers. They use the garage door openers to gain access into garages and homes.

I never program my actual home address into my GPS. The first thing thieves do is hit the HOME button on the GPS. The GPS takes the thieves right to the home. They use the car HomeLink or Lear remotes to gain access into the garage and home. They sometimes get into the home without forced entry because many people do not lock the attached door inside the garage to the home.

Cool previous career. Did you much work with Control4 or the other home automation brands?

Personally I don’t care for sun/moonroofs. Toyota/Subaru designed the double bubble roof into the 86/BRZ and Supra for more clearance for helmet.

Power seats are dead weight in a sports car.

At least Honda did not charge extra for fewer options like Porsche and other car companies do. Maybe they did at $44K?

Porsche is notorious for charging more for weight reduction. VW started taking market ideas from its cousin Porsche. When I bought my Golf R I did not want leather seats. The only way to get cloth seats was to get a Euro Package. The Euro Package eliminated the leather, cooled, power seats, sunroof and added an exhaust for $3800 extra. The weight of the moonroof can be felt but not to make a difference for me. I could not accept getting less equipment for more money so I went with the cooled leather power seats and moonroof.

I worked with a lot of brands over the years. HAI, OnQ, Crestron, Lutron...the list goes on. I currently use Homeseer. It is an excellent platform and is not cloud dependent.

This Accord mirror/setup does have the 'auto-dimming' feature?

In my use-case I realize I can handle the home-link being key-activated. Driving up to the door obviously has power; sitting in the garage will have the door either opened already or opened after starting the car.

Hi @GoZoner it is called “Automatic Day/Night Mirror Kit”. So yes, it have

Hi again, I still not understand why you are scar eof installing attachment kit? It is easy and there is a manual. Original autodimm mirror have different connector that this new with homelink. Creating own adapter harnesss to connect new mirror to vehicle connector is more work and strungle that installing $45 attachment kit. All needed is included, also new clip for A pillar garnish.

 

[GoZoner36]

You are right. I need to get comfortable with popping out plastic parts.

I thought if I got a dash cam I could splice in the mirror to its connector. (Like splicing by soldering or using wire nuts is any easier than popping some plastic…)

Thanks.
