33 years as a installer now just a retired old guy. Favorite thing to install/topic are remote starts/car alarms. Stop using test lights!!!

Thanks - From the wire side of the harness, that appears to be the 2nd wire from the left on the bottom. I will give that a shot.

mgoetz74,
Thank you so much that Speed Sense wire was spot on! Don't suppose there is a parking brake or park wire for the JBL system. Album Art does not work UNLESS the vehicle is in Park

Did you ever get an answer on the parking brake question? I'm look to enable album art as well.
Thx!

it took me 2 days to find information about the parking brake :( In the middle connector (30 pins) cut the pin 20 wire (for me it was black) and connect the part that comes from the radio to pin 24 (isolated GND). In this way you will foul the radio to think it is always in park. isolate the remaining part of the wire that was connected to pin 20 and that's it !
good luck.

Any chance this would also apply for my 2020 C-HR LE?

Any idea where the speed sense is on the hybrid model? Seems to be different.
Thanks,
