Unfortunately I’m not sure – the closest I could find is this Reddit thread that suggests the CX-5 one might work, but doesn’t sound super definitive. But the Mazda wiki page says the Mazda 6 should work so it should be one of them…

Do you or anyone know which harness will go with the 2019 Mazda 6? I purchased the “mazda” harness and it does not match my 2019 Mazda 6.

Now I’m trying to find out if the CX-5 harness matches my Mazda 6 better, or the CX-9 harness.

Thanks! And based on Trav’s comment here, I would try Sunnypilot which seems to allow you to change cars from the Settings menu. I haven’t tried it yet but I plan to, it gives more customization overall.

I am currently on openpilot 0.11. Will it automatically recognize my mazda and turn it into dashcam mode?

Love it! Thanks for the kind words and glad it helped 🙌

Comma Four is installed with Sunny Pilot and working great on my 2018 CX-5 GT. For anyone else concerned about the motor install, that was less time consuming than the actual Comma Four install.

Appreciate your blog, don’t know if I would have looked more into it without seeing your blog when googling. Cheers!

Oh awesome I’ve been thinking of trying Sunnypilot – this is the push I needed! Thanks for following up and glad it worked out 🙌

Yeah it’s much, much stronger. Before it was a gentle reminder that you were leaving the lane, but if you didn’t move the wheel to adjust you’d just keep drifting out of the lane. Now the LKA is strong enough to keep you in the lane without touching the wheel on most highway turns. (It depends on how fast you’re going – you can do stronger / wider turns the slower you’re going, since the wheel has to turn less every foot you drive to get you centered in the lane, if that makes sense.)

So with the new motor, if you’re going normal speeds, normal curve, the wheel will essentially be turning itself. If you hit a curve that’s too strong for it, the unit will gently beep twice to alert you that you need to “help” the wheel (i.e. apply more turning force yourself). If you were to do nothing and ignore it, you’d drift out of the lane but the motor is still applying turning force to try and keep you in, it’s just not applying enough because the curve is too strong.

So I basically keep my hands on the wheel and pay attention, and when I see a curve coming up that looks too wide or if the unit beeps, I apply a bit of turning force to help it out. But it’s essentially doing the thinking and turning for 99% of cases for me.

Hey, do you feel any difference with the LKA after installing the new motor?

Update: New EPS was installed from a 2023 Mazda purchased from the seller you linked to. Was a little worried about the difficulty of the installation but between a roof rack, trailer hitch, trailer light wiring and a Carplay install, this was the easiest. Install took about 20 minutes with a socket set using a 4″ extension. I am guessing it would have been a little more tricky using a standard wrench for the bolt in back.

Now just waiting on the Comma Four. Also reading up on SunnyPilot it looks like you can spoof other cars within the setting menu so don’t even need a separate fork (of the SunnyPilot fork) if you want to use that. Just choose CX-5 2022+ Mazda and it will work correctly with the new EPS.
