How did you wire into that CAN plug?


I just received a Kenwood DMX906S and Maestro Rr kit. I thought I saw an image that marked which pin was CAN but now I can't find that image.


I'm really hoping they improved this install because reading through all these troubles has me worried.

This post has details on the available CAN plug: http://www.ft86club.com/forums/showp...4&postcount=18


Installation is much easier now with SU2 harness and updated firmware.

Thank you very much. I have gotten the install mostly complete. I was sent an ACC-USB2 instead of the ACC-USB-SU2 that my car needs in order to connect the factory USB and AUX ports to the new radio so the install is sorta incomplete.


It isn't much of a problem as I am still waiting for the Metra harness that I need to connect to the 6 pin in the dash. I have plugged the OBD2 in for the time being to confirm that I am receiving CAN data and that is working great!


I love having tire pressures but what I am really puzzled by is that I am also receiving tire temperature. Does anyone know if this is direct temperature from a dedicated sensor or if this number is somehow inferred from a mix of variables?

Also, holy crap these factory speakers are hot garbage. They should have just deleted the rears and put both those dollars into the doors...

Yes they are garbage!!!

According to the link above, the Maestro OBD2 harness connects to the CAN High, CAN Low, and something called the K-Line.


Does anyone have any idea what the K-Line is used for or rather, what data is gathered from it?

Maestro said they're not taking any data from the K-line. I'm connected to just the hi/lo on the CAN and still getting data (although I may have lost tire temp, but as you noted I'm not sure where that's coming from, would have to be TPMS...?)

So I finally finished the install, I got that Metra harness with the 6 pin connector for the factory connector in the dash.


I pulled the pins out of the OBD2 connector and just plugged them into the correct locations on the 6 pin connector. I plugged the K-Line into the 1 empty/blank pin (pin 6) just so it wouldn't short on anything.


Seems I am still getting all the data I used to get. Tire pressure and temp are still working as well as all the throttle position, rpm, water/oil temps. Haven't noticed any loss of functionality.


I do see that some TPMS sensors can gather and send temperature as well. I had my doubts simply because the goal of this car was to be cheap and I didn't expect them to use "more than required" on something such as the TPMS system which is no more than a regulatory requirement.


I'm more than happy with the install. It went pretty smoothly and the only thing left to do is ditch this absolute trash set of speakers and amp. I really hate to add weight to this car so I'm going to try desperately to avoid the addition of a sub. Hopefully I will be satisfied with a 6.5 sub in the doors.

So I just tried installing the maestro -RR with the SU2 replacing the stock headunit with a pioneer 1440NEX.

I wasn't able to finish up the amp trigger signal so i had unplugged the headunit over the weekend while i was away.

I went back tonight to finish up the wiring and noticed my car battery was completely drained.

I thought the issue was fixed with the new harness.

Any ideas on what am missing or did wrongly?

Going to have to pull the battery (its a shorai with a custom mount that blocks the charge port when mounted) to charge it up before i can give this a go again. sigh.

I was able to relocate the mirror backup display to my pioneer head unit!! Brian at www.autoharnesshouse.com hooked me up with a custom harness for my MY19!https://uploads.tapatalk-cdn.com/202...331b96c402.jpg

I haven't tracked batt volts lately but I've left the car sitting for a few days with no issues. Check my posts #1 and #14 on the first page of thread for my wiring (because my brain can't remember at this point...:bonk:)

@Drifter X can you share a model number or other information on the harness you got from autoharnesshouse? I'd like to get one for my 19 TRD as well. I hate the backup camera display in the rear view mirror and would prefer it to appear in my aftermarket head unit.

Yeah i would also like the model number or something for this. I have the 19 as well and hate the small camera in the rear mirror.

Hello everyone! Email Brian: inquiry@autoharnesshouse
And let him know you need a custom harness for the 86 or Brz with the mirror camera. He’ll know what you’re talking about. [emoji1687]
