Looked briefly on the 'net and these forums but to no avail -- was wondering if someone knows the radio wiring scheme for the 2004 Heritage?

There are 14 wires in mine:

Black with Purple Stripe
Orange with Red Stripe
Gray with Blue Stripe
White with Green Stripe
Tan with Yellow Stripe
Green with Orange Stripe
Orange with Green Stripe
Blue with White Stripe
Black with Pink Stripe
Green with Purple Stripe
Black with Green Stripe
Red with Black Stripe
Black
and looks like a 2nd Black with Green Stripe

 

Go bug your dealer...the service guys should be able to give you a photocopy of the wiring diagram.
