These harnesses are warrantied and guaranteed to work, we provide excellent installation phone support and troubleshooting to ensure this reputation for quality, however they are non-refundable. Our Budget K-series Version 2 (K2) wire-tuck engine harness is nearly identical to its K2 Mil-spec counterpart with the primary differences being the type of wire used, the single black wire color and expandable loom used. All connectors and materials are new. Each connector is crimped with pneumatic heads to ensure an OEM crimp every time, then tagged with a white identification label for easy installation. All heavy interference circuits are protected and grounded with proper wire covering. Our engine harnesses are 100% quality tested pin to pin; And resistance checked to ensure no voltage fluctuations. These are the best harnesses money can buy. NO CORE is necessary when buying a harness from us! This harness follows an OEM style configuration meaning that you'll still need a interior ECU adapter for your chassis - see the K-Series ECU Adapter link and add-option below!

Perfect Fit for My Tesla!
Size: Upgrade - For Model Y Juniper/Model Y/Model 3
I’ve tried a few phone mounts for my Tesla, but this one stands out. It attaches securely without any wobbling, and the magnet is strong enough to hold my phone even on bumpy roads. The sleek design blends in well with the car’s interior, making it look like it was built for it. Installation was super easy—took just a few seconds. The charging feature works great too, so I don’t have to fumble with cables while driving. If you’re looking for a reliable, stylish phone mount for your Tesla, this one is definitely worth it!

Good mount for iPhone in Tesla
Size: Upgrade - For Model Y Juniper/Model Y/Model 3
Easy to use mount. Helped provide additional visibility while driving. Sticks really really strong to the surface. Also have an option of ac vent mount instead of sticking it on dash or back of screen. Strong durable material not plastic.

Versatile quality product.
Size: Upgrade - For Model Y Juniper/Model Y/Model 3, Size: Upgrade - For Model Y Juniper/Model Y/Model 3
The beauty of this phone holder in my Tesla Y is that it can be moved from corner to corner based on needs without worry of sticky glue issues… current setting is lower right corner and happy with things so far. Will absolutely update if my feelings change but so far I’m stoked with the purchase. Also the discount didn’t hurt either $$
