In reply to:
I have connected the wires up correctly
Based on your symptoms - I think not. You should recheck them very carefully. Did you get the wiring harness for the Toyota (this would not have come from sonic blue)? If not I highly recommend one (www.crutchfield.com)
The headlight wire is to dim the rio/empeg when the lights are on in the car. It may be called dimmer on wire harness. The antenna wire is to power a motorized antenna or remote amp turn on lead (not to be confused with the amp power lead)
I realize you are probably very new to the board so this is no big deal, but you will find that this type of question will get better response in the installation forum.
