My new-to-me OEM radio arrived today, so I plugged it in, connected the battery and confirmed it turned on, made noise, and the buttons worked.
Then I disconnected the battery again and did the TSB 25-005-13 Rev-A rewire. That was a little nerve wracking. I think I read and walked through the TSB instructions about 3 times before I made the first cut. I put it back together with ratcheting crimpers, waterproof shrink-wrap butt connectors, and covered it all with some Liquid Tape. No pictures, sorry. I was too into the work (afraid I'd lose my place) to take breaks for shots.
For the radio, I reconnected my Bluetooth module and the antenna, locked it all down, then put the dash all together and took it for a test drive.
Good news: The radio works. Good to great reception and sound. This was nice.
Bad news: I think the lights on the lower half of the radio are inoperable. Basically the row of channel numbers and the left side buttons. (Highlighted below.)
I honestly can't remember if these highlighted buttons light up or not. If someone wants to post a picture of OEM radio lit up in the dark, I'd appreciate it. (I want to be sure I'm not wrong before I contact the seller.)
When I went for the test drive, I still had the blinking CEL at startup. I doubt that drive had enough time/variables to reset the whole emission monitoring system. So who knows. (At least it runs?)
I was hungry and the wife was ordering pizza. It'll have to wait until later to get the OBD2 treatment.
