Installing Comma.ai / OpenPilot (BlueCruise alternative)

Worse case I’ll slice it and extend it
Update:
It looks like ATX 4 pin cable might work. I’ll order one today

Hi,
Do you have a link to the ATX extension cable that you ordered? Have you had a chance to try it out yet?
Thanks,
Bruce

The one I ordered from amazon got delayed, due to CrowdStrike outage. but then I found OBD2 extension that I purchased while ago, and it worked with my application.

OBD2 Extension:
https://www.amazon.com/OLLGEN-Extenstion-Diagnostic-Extender-Adapter/dp/B01AUN6XBG

ATX cable:
https://www.amazon.com/dp/B08N575KCR
Not confirmed if it will work, if its the same size (3mm), it might work with some modification.

I too am looking forward to updates on this project.

I can confirm that today I was unable to use Forscan with my Mongoose while the Comma harness was in place. Even with the device unplugged and the relay closed, I was getting timeouts. That doesn't really make sense to me, because it should be like solid wires with the relay closed, but I tried 4 or 5 times and couldn't edit a module. As soon as I removed the harness it loaded on the first try.

Probably means we need to remove the harness when taking the vehicle in for maintenance too. Very disappointing.

Was that with the new Q4 harness from Comma?

No, the legacy one. But they have the same design (just fewer wires in the new one).

I’m still waiting for my replacement harness to arrive. Still back ordered I guess. I’ll check with mine when it arrives and see if I have the same result.

I mostly run a private branch for testing, but I typically switch to bluepilot for trips.

Do you recommend any driving model?

I find very little difference between them to be honest. I think North Dakota is what I've run most recently.

Hey, everybody.
Am I right that I need comma3x, harness kit and just USB wires?
And it is theoretically not difficult to connect, can I do it myself or mechanic, I only need to pull wires through the whole car? No soldering or twisting?

And everything should sort of work?

just make sure the USB-C is USB3.2 Gen2
These are the one I purchased:
https://www.amazon.com/gp/product/B0BHHG4GGP
https://www.amazon.com/gp/product/B0BHHQRQWG

and I there is a video from EV vida, search youtube, or refer to the post from AjzRide a few pages back.

Okay, thanks. I get it. It's not all that hard to do.
I've read everything, but I'm not quite sure about the navigation.
Does autopilot now work in the city using navigation?
Or is it an "improved" version of blue cruise for now? Just lane centering and cruise?

It's an improved version of blue cruise (that works on any street, not just interstates) with the potential to one day support navigation (which blue cruise will never support).

Thanks. I will waiting.
I think it's been written here before that they used navigation. Was it some kind of fork and not a working version yet?
I can actually use the fork as well and possibly contribute.
