I have a wiring diagram for the factory JBL+Amp stereo system. I need to double check the wiring, but there are a few wires that are not accounted for in the wiring diagram - the dim wire and a few others.
But, as far as I know everything is hooked up identically to the other Sony hu. But, something isn't quite right with the volume. From volume setting 0 to volume setting 1 there is a substantial gain in volume. Then, past 3 it is distorted/overloaded. I'll let you know what I find out when I go thru the wires again.
From the wiring diagram, you a line from the 20amp fuse labeled +B, and you have a line from the 7.5amp fuse labeled ACC in, and you have a line coming from the hu labled Amp On.
thanks
