2006 XLT Wiring Harness and RAP ??

[Bercasto]

I have a 06 XLT v8 with advance trac and I'm wanting to install an aftermarket Head unit because using the factory unit with my Rockford forgave 1500watt amp and subs is a joke. It doesn't even pick up radio stations that I can pick up with a 20 year old Walkman. Anyway, I can't afford the expensive wiring harness atm so I was wondering what all I'd lose using the cheap harness and if there is a way to wire it up and still keep everything working normally? Thanks in advance!

Buy the harness and converter unless your time is less then a buck an hour. Its worth every penny.
