Usually, Red goes to + voltage (12V or battery) and Black to - , ground, chassis. If you've done that, and it doesn't turn on, you may need to add a line from +12V to the Ignition Sense terminal; depends on whether you have a single-piece dashmount radio, or a remote mount, which has a control head, and a large cable to a package in the trunk.

Need more info on your radio;

If it is a remote head model, you would need to apply power to pin 2 of the 6-pin molex on the back of the head. If it is a one piece unit (non remote mount) then you would need to apply power to pin 3 of the 15-pin accessory connector on the back of the radio.

I had to add the ingnition sense cable.

Or you could've reconnected the jump wire labeled "W101" on the circuit board. To make the ignition sense cable work they snip it. To use it without the ignition sense cable, it needs to be connected.

I was going to recommend that as well, but for most, that would be a little too involved as it involves finding the jumper and then either re soldering it or, if the bridge was removed entirely, making a new bridge and soldering it in place.
