Radio dead after telephone removal / OBC PPPP Code

Check what, the amp? See what? Image is like 200px wide, at that res, I could miss an elephant...

Looks to me like a red thing between those connectors. Sorry that is the only image for a e34 radio I found. Been scouring forever and saw that and wham! I got to check that thing.

Well my radio is different, does have a fuse was good but replaced anyways. No love. Treated all connections with stabilant 22A, put it all together and nothing. New thing is the radio theft light don't flash. Checked and changed the radio fuse even tho it checked out fine. Someone was definitely in here, sticker said something about some radio place, didn't take pictures tho.

Have to figure out what program actually works to decode radios since I have the one from the 540 sitting in the driveway.
