[img]Hi All,

This is my first post, but I have been reading the boards for a while now. I have exhausted my search on this board and the internet, so it's time for the experts...

I decided to remove the aftermarket radio installed by the previous owner and go back to stick. I have the stock radio but need to wire back in the GM connector to adapt back to the OEM radio. Seems simple enough right? Well, I researched on this board the various posts regarding wire color and destination. The problem I have is I do not see what I am expecting...first, from a color standpoint, I do not have a yellow or light blue wires. Second, I am not getting any constant feed from my orange wires. I am posting a pic (can't seem to do from Apple devices...advice?) of the wires I have and found I am getting power from one green, brown, and black wire when the truck is started or in the ON position. Note: the aftermarket worked fine, just looked like crap. The wiring in the dash looks completely nudes turned with the exception of the aftermarket harness that was installed. Going further back all wires are very neat and encased in the factory foam tape. Any help is greatly appreciated. As a side note, I seemed to have knocked out the odometer, speedometer, tach, and message center. I checked Ignition 0 fuse (10a) and it was fine...thoughts? Thanks!

Are you looking for a pinout of the radio plug

I know it's an old thread that got dug up, but just to remind people that are trying to go back to stock, there may be a bose amp/crossover wiring bypass in place too. It would be in the dashboard behind the glovebox. Designed to bypass a broken or unwanted bose amp/crossover. I forget the exact details, since it's been 15 years since I did mine.

Wow, has it really been that long. Dang.

Yep, I'm a grave digger too! I am going back to using the factory harness for speaker wires with my new JVC head unit. Since I won't ever be using the factor amp, can I just unplug the upper connector with the power wires and tape it off?
It's been hooked up for 21 years and I never bothered eliminating it. Now I want to do so.
