Do you own a test light or preferrably a digital voltmeter? If not, go purchase one, it will tell you whats wrong with pretty much every electrical issue you have.
 
make sure you have a good ground, The red and yellow wires are both hot wires make sure there hooked up. some times they wont come on if the yellow is not hooked up.

There should be two hot power wires - one switched and one always hot. The always hot is for radio memory. The switched one is the actual power wire. There is one ground, and sometimes, there is a power antenna wire. It supplies switched power to a power antenna from the radio. I've seen people hook this to 12 volt hot power by mistake because the wording is kinda confusing in the instructions sometimes.
 
Fuse good?
