I have an 2008 SuperCab with stock am/fm which I have changed to an 04 Heritage 6 cd with aux and so forth. It hooked up fine with the power/speaker wires.

There are two other harness hookups on the back of this new (to me) radio. Is one of them for the aux input. If so can I get that wire and then put a 3.5 mm jack on it to hook up my MP3 player?

I did something similiar in my Mustang or should I just take this radio and give it back to the guy and get an aftermarket HU with aux input?

Thanks guys for any help. I am new to the Truck world.
