I just got one from Ebay and now i want to install it , so i called bavarin autosport to get the harness from them and they said that they don't sell it by it self

, so i went to some audio shops and they want somethin from $150 to $250 to install it including the wires and every thing , But the thing is i wanna make it plug n play so i can remove it any time without any problems . My qoustin is does any one here have some pics of the harness and is it easy to make one like or not .
Thanks
