Here are two wiring harnesses for the popular small amplifier GM-D1400 by Carrozzia. The RCA input wiring is missing. For those who want it, here you go. Well, since some of the people who would acquire a unit missing wiring probably don't want to be scrutinized, I'll allow purchases without comment and ship anonymously with shipping included. Buy it discreetly. Starting the price at this level for now. I may lower the price at my discretion. However, I will ignore and delete those who try to haggle. Feel free to leave interesting comments even if you don't buy it.
