The connector used on the body harness for the ASC:

Here's the list of wire-to-wire connectors that are compatible (note you'll need to buy the right pins)

Constant B12 works, and the IGN wire is +12 when ignition is on (not in ACC, it seems)

Thank you so much! I'll do that once I get my own 2022 car and verify them.
I'll also do my best to find out the IDs and encoding for other channels I'm interested in.

Parts list for the ASC connector/patch harness:

Male connector (plugs into factory harness):
- AMP/TE Connectivity Connector Housing P/N: 1376106-1 (Quantity 1)
- AMP/TE Connectivity Pins P/N: 1376109-1 (Quantity 8) - I'd suggest ordering a couple of spares though in case you mess up crimping

Female connector (same as factory harness if you're making a patch)
- AMP/TE Connectivity Connector Housing P/N: 1318386-1 (Quantity 1)
- AMP/TE Connectivity Pins P/N: 1123343-1 (Quantity 8) - I'd suggest ordering a couple of spares though in case you mess up crimping

I used this wire: https://www.amazon.com/gp/product/B0...0?ie=UTF8&th=1

I used this RJ45 breakout (for RaceCapture Track Mk2, you'll use something else for other devices): https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Use something like this to crimp the connectors. It's fiddly and annoying but way cheaper than the "right" tool: https://www.amazon.com/Qibaok-Termin.../dp/B089LW7MWT

If you're wiring to a breakout like I was, this will work to make the ferrules on the wires. Way nicer to insert than stranded wire twisted together or whatever: https://www.amazon.com/TICONN-Insula...dp/B09F94TPRV/

My patch harness (made a second for a friend that I owe a favor to):



My RaceCapture "install" after I routed the RJ45 cable along the passenger side rocker under the carpet, down in front of the seat, and out the flap that exposes the chassis VIN.



Data into SoloStorm!



Matching temps on the dash for comparison:

Awesome, thank you so much @DocWalt!

It doesn't get much easier to access than the ASC connector. Taking the radio out on a Gen 2 is "tear the entire damn dash apart" soooo.....

Since I've figured out the most relevant parts of the CAN bus logging (not without @DocWalt's help!), I decided to document them on my various GitHubs.

Connections:
https://github.com/timurrrr/ft86/blo...an_bus/gen2.md
[will also have more data on various CAN IDs in the future]

IDs and equations for the most useful data channels:
https://github.com/timurrrr/RaceChro...b/ft86_gen2.md

How to make a DIY CAN bus reader if you don't want to spend $$$ on an AIM:
https://github.com/timurrrr/RaceChronoDiyBleDevice
[The project is being actively updated with 2022 specific tweaks.]

Demo:

Thanks for taking it and running! Glad to help get the ball rolling with some of my local friends helping out
If RaceCapture ever gets little-endian data working properly I can keep helping sniff data out!
