You need help with the power antenna install let me know. I just put mine on.
One thing to be aware of, your stock anteanna wire doesn't have a female connection on the end that connects to the stock antenna. It's sorta like an RCA plug instead.
You can get an adapter from Wal-Mart that almost fits, but you have to cut some metal off it. Or you can get a new section of anteanna wire with a male/female end.
Or I have a spare length that'll work. The guy I bought mine from sent me two lengths, and one was enough.
