I have a 525 1991 and I installed a sony deck. I am having problems in finding which colour wire do I connect to to make sure my new unit remembers its pre-sets this is driving me . I have been to sites that show pics but none of them look like my wiring set up from the old oem deck. So please if anyone has the time or the know how help me out. This would be greatly appreciated.
THANKS
