Annoyed with overpriced cables using X437A connector for later Model S and X cars, we made our own.

OVMS Data Cable for Later Tesla Model S/X <https://www.fasttech.com/products/0/10070138/9730443-ovms-data-cable-for-later-tesla-model-s-x> US$14.50, including basic shipping.​

The cable provides access to the three most useful CAN buses, for later Tesla Model S and X vehicles using Sumitomo 6098-5622 (X437A) connector. It also exposes CAN2+Body bus (but requires custom replacement of DB9 connector to use). Pinout: OVT2 6098-5622 DB9-F Signal

Enjoy.
