Ive got a wire that runs from the dash up the passenger side then across to where the antenna is, just wanting to make sure that this is the antenna wire that goes to the back of the radio? I tried to follow it but cant see where it goes behind the blower motor... anyone?

 

you sure it doesnt go towards the fuel pump, if you didnt peel off the carpet its hard to tell.

 

The fuel pump wire in my car is blue, but where that comes out from the rear speaker It goes back to the antenna area, I have no interior in the car at the moment

 

Could it be the wire for the cargo light? My S5 had a cargo cover and a light that is right there by the antenna (it also serves as a base for the cover).

Of course your antenna wiring is there also.

 

I went through and found the wiring for the antenna and started pulling, its deff the antenna wire
