2018 BRZ - firmware but no install docs

Post by dvdan » Wed Nov 28, 2018 5:11 pm

Hi,

I just bought a SW for a 2018 BRZ. I was able to download firmware for my car, but there is no wiring diagram offered. I know where the 3 SWC wires are on the harness (pins 21-23 of the 28-pin connector), but no idea which to connect them to on the Maestro SW. Anyone care to help?

Maestro's Purple/Red will go to Pin 21 - Pink
Pink/Red will go to Pin 22 - Blue/Yellow
Black/White will go to Pin 23- Light Green

I'm sorry about the missing info- i will have it fixed today.

Thank you for the quick response. I connected as you described, and it's not mapping correctly.

Here's what I get;
Source = MUTE
Track down = volume up

no other buttons work.

Another vendor's SWC for this car (which also didn't work) said pin 23 should be connected to ground, for what it's worth.

We are supplying ground on Pin 23 :-) That connection is fine, or none of the buttons would work.

It might be best if you call into our tech support line when you're in the car for further troubleshooting. It is much easier to get to the bottom of things in real-time, as opposed to in writing on a forum.

Thanks,
