Just picked up my M3P a week ago and will be getting a lot of mods done to it over the next couple of months (winter here in Michigan). The Homelink module is not part of the latest Model 3 builds, nor an option at time of purchase despite it being on Model 3s for the first few years. So, after purchasing the module from Tesla, then looking for installation instructions, I quickly realized that Tesla needed to do put this in as I did not know where to disconnect high voltage.
I found that the module is installed just behind the bumper and in front of the funk latch, requiring the bumper to be slid out a few inches. Given the vehicle is brand new, I was going to get the module installed, then let the tech do the update to software so it is recognized. I'm glad that I didn't. So to back up a step... I checked the Tesla app to schedule an appointment - it was Monday at 4p.m. I thought I would discover available appointments a month or so out, but nope. The next morning was available. So, Tesla arrived mid-morning in my shop and it didn't take too long.
First step, remove frunk plastic insert. Then remove a couple of small bolts in the front wheel wells that holds on the front bumper. Remove a handful of small bolts along the front lip that attach upper lip to vehicle. Then carefully slip the top edge of the bumper outward, giving enough space to get inside the center front.
Before attaching the homelink module, the tech disconnected 12v negative lead from battery, then the high voltage connection located inside the passenger seat. Once disconnected, he snapped in the module, connected the cable and then was able to reconnect power sources. From there, connecting up his laptop to the car and software was ready and homelink was available. Thank you Tesla, should have been included in the vehicle. But this is a feature that is very nice to have, especially when integrated into navigation before my office and home.
