I have the hi-lo converter an amp and a sub, but i can't find any free wiring diagrams for a '97 f-150, i would like to now where to connect the blue accesory power wire, and where the right and left speaker positive and negative wires are in the factory harness with the factory premium sound.

 

Go to walmart and get a reciever wiring install kit, and match up the plug to the wiring codes, then when you are finished, return the kit to walmart! Easier than looking up all that stuff on the net, anyway.
