I need help with finding out where the second part of the stero plugs in to the main section .I changed the heating core the other day,and when I pulled the heater box down the second half of the raido came with it .I put it aside and finisshed the heater. ( not as bad as I thouhgt ) When it fell it came unpluged ( heavy black cable with about 8 prongs on it ) and I can't find out where it goes.It's hard to see so I'm mostly feeling for it. Anyone know where to look ? Thanks Bob
