blaupunkt rpd 545 diagram needed

not sure if this is the right forum to post this in, but does anyone know where i can get a free diagram from the radio connections coming out of the radio? i sold the car my blaupunkt rpd 545 head unit was in and forgot to take the harness out when i took the radio out, i dont have a credit card to order any diagrams or have access to one, so im stuck... i need to know which pins are for what... i looked on the circuit board and that info didnt work, almost fried the unit... i have tried contacting blaupunkt also, and they told me where i could order a harness from, but again, no credit card or access to one... so does anyone have access to a diagram they could forward me?   ccrashxburn@aol.com   is my email

yeh, i have the manual downloaded already.... but when you look at the back of the radio, where the connector plugs in, i am missing that connector.. the main harness... so what i am looking for is the pin diagram, to specify which pin is for what {power/ground/speaker} stuff like that... maybe it is called a circuit diagram, i am not sure... but i am basically trying to make my own harness.
