    Model 3 Wiring Connectors

    Does anyone have the list of connectors used in the model 3 wiring harnesses with the names/part numbers? I have the Tesla codes for the connectors that I need from the wiring diagrams but don't know what the standard names/numbers for these are to be able to order online. Thanks

    Does the battery outer case get very hot?

    Hi: Does anyone know if the bottom of the Tesla battery case gets hot to the touch during use? I am considering running a conduit to carry a dash cam wire from the rear view mirror to a camera on the rear bumper. I can take a super smooth route directly attached to the battery cover or a...

    Wall Connector/Charger Daisy Chaining on Separate Breakers

    Hey all! I'm working through the plans for adding two wall connectors to my garage for our soon to be delivered X and upcoming S and have run into what seems to be an obvious solution except for perhaps limitation of the wall connector setup. The goal is obviously max charging speed within...

    DIY: Troubleshoot "dead" horn on 2014 pre-facelift model S

    I have had my horn in for service a couple of times at Tesla's because it stops working, and of course starts working again at the shop. They "clean the contacts", whatever that means but since it's already working when they have it in- house they are never able to fully troubleshoot the issue...

    I'm currently trying to do a LED headlight retrofit on a 2013 P85. I need help finding the wiring harness part number for the headlights on a 2017 Model S. I have the headlights on hand and would like to try to change the harness out and reprogram the vehicle vs opening the headlight and...

    Aftermarket accessory install: Source of 12v power only when phone w/app / fob is detected in range

    I am working on testing a kick sensor for the Model 3 for the frunk and realised the 'trapped person' button inside the frunk is constantly active, meaning tapping this button to pop the trunk with the kick sensor also allows opening the frunk while the car is locked. I am aware that there is...

    Between my breaker panel and my garage there is a 40' run of crawlspace. I have a 90A breaker and 2AWG wire running to my HPWC. I will use conduit for the run in the garage leading up to the HPWC. But how about inside the crawlspace (between my breaker panel and garage)? Is conduit required...

    Which AWG Wire? Someday want to upgrade 14-50 NEMA (50A breaker) to wall charger (90A breaker)

    I'm 4-6 weeks out from getting my MX (100D). For now I plan to wire a 14-50 receptacle (50 Amp breaker) because it is cheap (relative) and easy. At some point down the road I'm hoping to score a referral and get a free wall charger (or maybe find one on Craigslist or ebay - anybody out there...

    Improving the Tesla Model S Alarm

    Back in 2005, I installed a shock sensor to the hood latch alarm of my old Infiniti FX35AWD primarily because the alarm in my old FX (like my Model S) only activates when a door, frunk or trunk is forcibly open, not when there is substantial motion detected. With the help of a friend, we...

    Installed a hitch and wiring harness on my M3

    Installed an Eco Hitch on my M3. I also wired a 4 prong harness for about $25 in parts. The wiring is also completely hidden. It accelerates like I’m not pulling anything. The trailer has standard bulbs and works fine but I’m going to switch them out for LED.

    Question: Routing of purple wire from rear hatch release switch

    I'm trying to tap in to the purple wire coming from the rear hatch trunk release. This is the switch just above the license plate. I'm hoping to find the wire somewhere in the trunk, but no luck so far. Does anyone know if it's there and how to locate it? I'd prefer to tap into it in the trunk...
