I have an old scion pioneer radio and want to put it in my work truck, any idea how to wire up for ipod and aux wires on the back of radio?
I already have a reverse wire harness, but its only for power and speaker wires.

 

you would need the harness out of a scion that leads to the ipod connections, aux wire can just be run off a switch from the fusebox or battery

 

Yeah.. that'd work. Anything beyond what Murphy said there ^^^
you would just need a wiring schematic for the vehicle you're putting it into and verify what wires are used for what. It's fairly straight forward.

 

The aux and iPod harnesses are pretty much proprietary. You'd have to snag one out of a wrecked xB or see if the dealership could supply you. But if you went the dealership route, the cost would be equivalent to a nice aftermarket unit.

 

any scion harness will work they are proprietary
