Tesla Model Y wiring efficiencies questioned in latest Munro teardown

Sandy Munro took the opportunity to show the Tesla Model Y’s new wiring structure, however, the Detroit automotive veteran noted to be “kind of disappointed” in some of its design.

“What I see here is a nice application of the wire troughs and candy striping…But unfortunately, there’s just as many wires; the wires are just as long,” Munro said.

In July 2019, Tesla published a patent that aimed to improve the wiring, power, and communications systems for its vehicles by reducing the amount of wires found within a car. The idea for a new wiring architecture was needed as many miles of cables can be located within a vehicle, all of which need to be installed by humans and not by machines. The installation of these power lines can take a significant amount of time when needed in excessive lengths. Thus, Tesla maintained it would be decreased from 1.5 kilometers of wire in the Model 3 to just 100 meters in the Model Y.

A Tesla vehicle’s wiring system is responsible for powering everything from turn signals and interior lights to the vehicle’s charging system. It consists of both 12-volt and 400-volt wiring, and the length of wiring needed varies from vehicle to vehicle. However, one thing remains consistent: efficient wiring is crucial for faster production speeds. However, a reduction of wiring also can contribute to reducing the vehicle’s weight as miles of power cords can be present within a car’s power infrastructure.

Reducing the wiring is something Tesla worked on when developing the Model 3, as the Model S contained around three miles of wiring to power its various systems. Tesla halved this amount of wiring with the Model 3 but aimed to decrease it even further when the Model Y was announced. Munro claimed he did not see less wiring, only a more organized wiring architecture. The new design is still an improvement from the Model 3.

Munro then suggests other strategies that Tesla could have used to increase the effectiveness of its wiring systems without using excessive amounts of wires. One of these strategies is called “communications over power,” or, more commonly, Power Line Communication (PLC). Munro explains this system reduces the number of wires by allowing for the implementation into a single power line, instead of many separate lines that all have different functions.

One of the most significant differences between the design of the Model 3 and Model Y was supposed to be its wiring system. In a video from Tesla owner-enthusiast TeslaRaj, the Model Y owner’s manual shows a single track wiring system, where the Model 3 had two tracks. The new single-track system could hint toward the overall design improvements in the Model Y wiring architecture.

Tesla’s wiring design was improved through a more organized harness setting within the Model Y. While the amount and length of the wiring system appeared to be the same according to Munro, these initial changes could end up being a catalyst to a more efficient and less puzzling architecture. Of course, fewer wires would be a dramatic step toward manufacturing efficiency, but this should come with time as Munro’s suggestions just might be accounted for in future Tesla vehicles.

Honda and Acura electric vehicles will soon be plugging into Tesla’s Supercharger network, with approved NACS-CCS adapters rolling out to Prologue and ZDX owners in June 2025.

This provides Honda and Acura EVs access to over 20,000 Superchargers across the United States.

Adapters Ensure Safety

Starting June 2025, Honda Prologue and Acura ZDX drivers can acquire a Honda-approved NACS-CCS DC fast-charging adapter at authorized U.S. dealerships, with pricing set closer to launch. Tested for safety and compatibility, it’s the only DC adapter that Honda recommends for its EVs at NACS stations, as noted in a press release

Ryan Harty, assistant vice president of Sustainability & Business Development at American Honda Motor Co., Inc., shared his thoughts on the matter. “Adding Tesla Supercharger network access to the charging networks already available to our EV customers means industry-leading fast-charging access for Honda and Acura EV drivers,” he said.

Tesla requires approved NACS adapters at its Superchargers, and Honda strongly recommends that Prologue and ZDX owners use approved adapters. Honda also noted that damage caused by using unapproved adapters may not be covered by cars’ limited warranties.

Honda’s Big Charging Vision by 2030

Honda’s not stopping at Tesla’s network. By 2030, Prologue and ZDX owners are expected to tap roughly 100,000 DC fast-charge points across North America, blending Tesla Superchargers with IONNA’s new network, EVgo, and Electrify America. 

“By the end of this decade, we strive to provide Honda and Acura EV drivers with the most convenient and easy charging at more than 100,000 charge points nationwide, helping people choose to purchase an EV for the many benefits of driving one,” Harty stated.

“Tesla Takedown” movement plans 500 protests in 277 stores, Superchargers

Rep. Jasmine Crockett (D-TX) stated that March 29 is her birthday, and “all I want to see happen on my birthday is for Elon to be taken down.”

The “Tesla Takedown” group is aiming to hold its “biggest day of action” in over 277 Tesla stores, as well as Supercharger stations.

During a mass call on Wednesday, organizers, filmmakers, members of Congress, and other key individuals banded together to call for a mass demonstration against the electric vehicle maker this coming March 29, as noted in a report from The Verge.

Tesla Takedown

The Tesla Takedown movement emerged from critics’ opposition to Elon Musk’s increasingly political nature, his close relationship with U.S. President Donald Trump, and his work with the Department of Government Efficiency (DOGE), which is aimed at cutting unnecessary government spending and waste. Members of the Tesla Takedown movement have targeted the EV maker since a notable portion of Musk’s net worth is tied to his Tesla holdings.

Unfortunately, protests against the electric vehicle maker and Musk have become increasingly violent, with Tesla stores being shot up and vehicles being burned in acts of arson. Supercharger stations have also been targeted in arson attacks. Tesla owners’ vehicles have been vandalized and set on fire as well.

Amidst these attacks, Trump has noted that he considers such actions as domestic terrorism. Attorney General Pam Bondi has also noted that those behind the arson and vandalism against Teslas will be caught and persecuted.

“No Conspiracy,” but Still Wishing For Musk Takedown

During the hour-long call, actor and filmmaker Alex Winter, who promoted the Tesla Takedown movement on BlueSky, stated that there is no conspiracy to take down the electric vehicle maker. “There is no conspiracy, there is no well-funded cabal. It’s just Elon Musk who has taken Tesla down,” he said.

Alice Hu, executive director of Planet Over Profit, noted that protesters are looking to hold over 500 events across the world on March 29, with 277 Tesla stores expected to see demonstrations. She also stated that protesters should feel free to demonstrate at Supercharger stations. 

“We need to show Elon that he can throw a tantrum online because his stocks are tanking. He can get Trump to put on a humiliating used car show in front of the White House. These wannabe authoritarians can try to intimidate us from exercising our First Amendment rights, but they can’t stop us from fighting back,” Hu said.

Rep. Jasmine Crockett (D-TX) called for participants to fight, though she was quick to state that protests should be nonviolent. “The things that we’re fighting for, we are fighting for our country. We’re fighting for democracy. We’re fighting for our freedoms. And when I say fighting, I’m saying that figuratively. Obviously, everything that I am promoting is nonviolent,” she said. Interestingly enough, Crockett also stated that March 29 is her birthday, and “all I want to see happen on my birthday is for Elon to be taken down.”

Tesla CEO Elon Musk has announced two measures the company is taking to fight the vandalism that is going on at showrooms across the country as vehicles and even structures have been lit on fire, spray painted, or damaged by various means by those who oppose him or the automaker.

As attacks against Tesla owners and even the company directly continue to occur across the country, people have been wondering what the company will do to fight back. After President Trump and other members of the administration stated that attacks against the company would be treated as domestic terrorism, many thought things would cool down.

However, things have only intensified. Although several of the perpetrators have been arrested and are facing consequences, it seems the severity of the attacks has only gotten worse. Things like Molotov cocktails have been employed by protestors to show their distaste for the company.

Now, Musk is detailing several things Tesla is doing at its showrooms in hopes of ending everything that has gone on and persisted due to the resistance from those who oppose the automaker.

Musk says that Tesla is now ramping up security at its showrooms and is now using Sentry Mode on all vehicles to help catch perpetrators in the act.

We have seen security beef up in several high-profile locations, including Tesla’s Las Vegas location on Sahara Blvd., where Las Vegas Metro Police were spotted yesterday keeping things under control:

Additionally, Sentry Mode has already done a great job of catching several perpetrators in the act, like this one who was recently caught, arrested, and now faces up to 18 months in jail for keying a swastika in a Tesla:

Hopefully, these two measures can eliminate most of the issues Tesla has had at its showrooms. If not, there will likely be follow-up measures utilized by Tesla in hopes of ending this senseless vandalism.
