Radio Wire Help

[tallyF350]

Can some one tell me what these two wires are for on the radio wire harness plug? One is red-ish and the other is black green tracer.

they both had ttabs on them (from a previous owner) going top a wire that was not plugged into anything, just hanging under the dash. I was cleaning up the wires and removed the ttabs and now the radio wont turn on. I checked the first wire to the left of the red and it has power. when I unplug then re-plug thes harness into the radio I can hear the cd changer spin or move....

Stock Deck?

Just some ideas: aftermarket radio alarm, module that allows stock stearing wheel controls to be used with aftermarket deck, remote wires to an amp (usually blue though), again these are just guesses sorry.

Yes it is the stock radio.
