This was on an '11 since the 020 was spec'd for MTS. You can still get parts for cheaper online but that is what this dealer was selling them at .

I either forgot or had not previously seen the new crawl control graphic when CC is engaged on a 2020.

EDIT: Or donate a TIS Test Drive Code to me and I will go in and explore for info
Anyone subscribed to thread with a TIS subscription that would be willing to search out the 2020 wiring diagrams to see how crawl/MTS is wired up?

For 2020 too early to tell but looks like Crawl/DAC Switch simply goes straight to the skid control ECU.
This could go a few different ways or other unknowns...
Maybe a simple crawl switch replacement with ZPC gets you both Crawl and MTS? If not MTS is brought about with something else?
Or a more expensive requirement this go around '20+ of also a new Skid Control ECU which is around $1k or more?

Not known yet. Things are not wired the same way. It could be more expensive, less expensive, more plug and play, or less p&p. Existing retrofit hardware for 10-19 models will not work for 2020.

There are two new brake booster assemblies that show up for 2020. Price is same... probably like other years where it didn't matter between DAC or Crawl.

I wouldn't give up hope yet...
We need to find out if 2020 ZPC (Zero Point Calibration) for Crawl or DAC is the same procedure.

Looks like ZPC via TS is still there but wire/OBD isn't ... not saying it won't work but not in FSM.

Matt@OEM states that 84970-60450 is indeed the new version of crawl control switch. Only two in North America right now and both would need to be obtained from Canada.
I'm not sure we will be able to absolutely confirm this will enable Crawl and MTS through wiring diagrams alone. This will likely require someone trying it out with fingers crossed.
One could also in theory test out along the same lines as John00's budget crawl but perform steps using the connector and jumpers currently attached to the DAC switch

2020 Crawl Switch does not connect to the same ECU. Former ECU is no longer present and it appears all logic was moved to the skid control ECU off of the master cylinder.
Combination Switch Assembly = Crawl Switch
