You're always welcome. Sorry it isn't more clear.Thanks, John! You are always so helpful with the electrical stuff!
I pulled the plugs and checked that all the pins are straight. When I hit the mute on the steering wheel the stereo shows on the display that it is muted/unmuted. I'm having a hard time reading that second photo. I'll try to check those pins in the morning. I'm done with this beeyotch for today.
Do I need to check the output from the back of the radio, or the X1 plug?
I think you are going to have to go into the back of the connector so that you can check it while it is plugged into the radio.
The connector pin map is really all you need, the schematic is just to reinforce the pin labels.
