I just went and tried to hook up the radio, atleast the power to see how it looked like, I connected the ground (maybe) , I connected the only purple wire to teh ground on the radio, then I connected the power, this radio has a Red and a Yellow for power and also the 240 has two of the same power cables, maybe be different, tell me if im wrong
Well I connected the power and alternated between the combinations of the red and yellow wires conccted to either of the two power wires on the 240
Well none of the conbinations worked so I gave up, I started up the 240, and to my surprise when I started it up, the windshield wiper also started up to

WTF?!?!
im not an expert with electronics as you can tell
but what the hell happened
and how do I get the damn radio to work?

any help with this would be greatly appreciated
Thanks guys
