Yukon 2000 Radio

[Daniel1999]

I'm swapping my factory radio for a aftermarket radio

I'm installing a single-din Dual DV735MB with the flip up touch screen, i have the single-din dash kit, antenna adapter and the big harness for it, but when i unplugged the factory radio to replace, i noticed that there was a third smaller, single row harness plug right next to the antenna, what is that (there is a plug in my suv that was connected and i can't find details anywhere) plz help

That connector is connects to the tape deck or cd changer. It also has a pink wire that you need to connect to the remote turn on wire on your new radio (might also be called power antenna wire) if your truck has a factory amp. (if you have a sub in the back, you have a factory amp)
