Just a heads-up : The magna radios earth themselves through their casing and the mounting brackets.
This means there is NOT an earth wire in the Magna car loom plug. Just find a metal screw/nut under the console area for the Pioneer to earth to. IE: the black wire coming from the HU should not connect in the car loom connector - just solder a loop or fork connector to the black wire and find a metal/metal spot behind HU/dash to ground the HU.
