Let’s talk HomeLink—and how to install it yourself on a 2024+ Model 3 Highland.
Back in the day, Tesla used to include the HomeLink module from the factory (we see you, 2018). But now? It’s a paid add-on, thanks to the move toward subscription-based garage access via MyQ. Some people love that. Some people… not so much.
If you’re the DIY type (hi, welcome), installing your own HomeLink module is absolutely doable—and we’re here to show you how we tackled it.
What You’ll Need
-
Tesla HomeLink module ($220 from Tesla or around $120 used)
-
10mm and 8mm sockets
- Ratchet + extension
-
Clip removal tools
-
A lot of patience
-
Optional: a multi-tool, some caffeine, and a decent playlist
Step-by-Step HomeLink Install: Model 3 Highland Edition
1. Start by removing the Frunk
We popped the frunk open and started by removing the plastic covers and trim around the frunk tub. Once you pull the side panels and undo a few 10mm bolts, the tub comes right out. Make sure you remove any tools before lifting it—you’ll thank yourself later.
You’ll see the washer reservoir underneath. On the Juniper Model Y, the HomeLink harness was on the driver’s side. On the Highland? It’s on the passenger side. We unbolted the reservoir for easier access and found the HomeLink connector cable neatly taped down.
2. Connect the HomeLink Module to Test First
Plug in the module—it only fits one way—and get ready to activate it. Head inside the car, go to the Service menu, and you’ll see a HomeLink option.
Run the HomeLink retrofit process via the diagnostic gateway unlock. Boom—it’s live! Now, test the connection before doing any reassembly. If it works, you’re golden.
Now for the Hard Part: Mounting the Module
Let’s be real: the hardest part of this install is mounting the bracket. Tesla didn’t exactly make this step plug-and-play.
Here’s what we ended up doing:
-
Removed the front bumper (yep).
-
Found the best spot for signal transmission: behind the bumper but as close to the composite surface as possible.
-
Realized there’s no pre-threaded bracket location.
-
MacGyvered a mounting solution with a self-made bracket, a one-inch bolt, and a bit of finesse.
-
Secured it with super glue and a lot of hope.
Why this location?
The HomeLink module is a wireless transmitter, so signal strength matters. Tucking it too deep behind crash bars or buried metal weakens the range. We kept it close to the surface behind the bumper for optimal performance—and it worked beautifully.
Final Thoughts: Worth It?
Absolutely. If you want a one-time payment and no subscription, this install is 100% worth it—even if it breaks your back a little.
We’ll probably 3D print a cleaner bracket solution for future installs (stay tuned). But even with the jerry-rigging, everything turned out solid, secure, and functional.
So if you’re tired of fumbling for your garage remote or paying monthly fees, installing HomeLink in your Model 3 Highland is a fantastic upgrade.
You can also have the Tesla service center install this for you if DIY isn’t for you or time not on your side. It’s about $350, including the part!
