Need power antenna help
 

I have a 2003 Spyder Gt with the Infinity radio and had to replace the power antenna. I replaced it with a Metra CF-PW22 from advance auto. Need help wiring it. The antenna has two wires, red and blue. The wiring harness to the old antenna has 5 wires. Any idea how to hook it up would be a great help. Thanks in advance, Gary
