For sale, I have 2 (both have sold) Lukas/xnor harnesses for Gen 1 R1S/R1T including longitudinal upgrade and secondary USB cable. These harnesses were purchased through xnor.shop in October/November 2025 and worked flawlessly in the vehicles until they were recently replaced with Lukas's new "extreme dev kit".
Price for 1 harness w/ longitudinal upgrade is $60 shipped by US mail and payment through PayPal (incl. PayPal buyer protection); or $50 cash and local pickup near Boulder. Sales final, no refunds. Support available through the xnor discord server, see the link at the top of xnor.shop website.
To be clear, $60 buys half the items in the picture: 1 harness with longitudinal upgrade, 1 ODB-C extension cable, 1 fuse tap, 1 secondary USB cable.
Compared to the standard comma harness, the Lukas/xnor harness bypasses the problematic AXM power connection and relies on a fuse tap.
As for the longitudinal upgrade, when used with Sunnypilot and derivative forks, it allows the Comma to control speed instead of Rivian ACC using similar controls as stock (cruise speed using the steering wheel buttons, following distance aka "driving personalities" using the scroll wheel). It also gives Sunnypilot access to the Rivian’s blind spot monitors (BSM) when coordinating auto lane changes.
