IM TRYING TO WIRE A PIONEER DEH-5 TO MY STOCK WIRES IN MY 1996 VOLKS JETTA. I CHECKED OUT THE WIRING DIAGRAM ON THE JETTA AND SOME OF THE WIRES DID NOT MATCH UP,LIKE FOR INSTANCE THE SWITCHED WIRE ON THE DIAGRAM SAYS THAT ITS THE ORANGE WIRE BUT IN THE CAR THERE ARE TWO ORANGE WIRES ONE WITH A RED STRIPE AND ONE WOTH A WHITE STRIPE SO IDK. THE OTHER ISSUE IS THAT IF I HOOK UP THE CONSTANT POWER AND THE GROUND WIRES FROM THE CAR TO THE HEAD UNIT. IT SHOULD TURN ON CORRECT OR AM I FORGETTING SOMETHING?

Hi, the plain orange wire is the power wire. The constant wire is only for maintaining the station presets--it does not power the unit on. The other orange wires are for speakers. See the full color code below, and let me know if you have any more questions.
