Yeah the problem is the old cars has HSCAN 1 and HSCAN 2 read through the 14 and 6 pins. Then had MSCAN on 3 and 11. Now HSCAN 1 is on diag 1 (14,6) and HSCAN 2,3,4 and MSCAN are on diag 2 (11,3). Connecting to both busses is fine, just messy. Do any of those CANcrocodile things (contactless CAN connectors) function with the mk3 RaceCapture?the OBD2 connector should still work for a can bridge - when you splice in on most fords, its into basically the same wires.
I hadn't touched any 2019+ cars with RC, but even if the older S550 preset doesn't work, its not terrible if you have a helper to do some CAN sniffing to reverse engineer wheel speeds, steering position, TPS and maybe brake pressure: https://www.autosportlabs.com/rever...tle-position-brake-pressure-and-wheel-speeds/
