I'll be replacing my stock radio tonight and was wondering if there is a code or something that you would need if someone else wanted to buy and install my stock radio in their truck? Its an 05 Pioneer with the sub output.

 

no that is only with hondas and gm's

 

Your radio should go in another Ranger or Ford Double Din with no problem. Just as long as the wiring harness is the same and the bezel is Double Din.
