Ladies and gentlenerds, the cat has escaped the bag: We have new wiring schematics for Model S! Woo-hoo!
Interestingly they're called "October 21, 2017"... Which is two months from now... So naturally there's some speculation that "October" could be a
typographical error and that it should've read "August".
Since
August 21, 2017 was yesterday.
And since the previous wiring diagram was released in
"October" 2016.
And since Tesla has never released anything that early before.
Who knows. Fatty-fat fat fingers, maybe.
Anyway: Autopilot "HW 2.5" -
yes: Tesla actually calls it that in the schematics - seems to include the following changes:
1) "Gen3" Power Steering ECU with redundant power supply from a new E-fuse box in the frunk. (The E-fuse box itself is a pretty big HW-change as well, but I won't go into that.)
2) Rear view camera wiring/connectors has changed in the Autopilot ECU. Video signal still goes directly from rv-camera to the ECU (same as ap2.0), but now there's a "splitter" on the ECU side that for some reason sends signal out to both the MCU and to the ECU itself! So now there's two BUC inputs; one "Splitter Rearview Cam IN" and one "APE Rearview Cam IN". Don't ask me why. Anyway cudos
@verygreen for noticing this in the SW-code long ago.
3) New radar sensor from Continental ("Radar Front Conti") with "primary" and "secondary" CAN-signalling to AP2.5ECU. Exciting!
4) Different fuse location for the 30A Autopilot ECU Primary power (F133 > F214). The 10A Autopilot ECU Secondary power is same as before. Not so exciting...
Non AP-wise, I also noticed a new
"Charge Port ECU" that was not in the 2016-diagrams at all. (WTH?)
Well that's about it. No interior/cabin camera and still no HUD for you.
