Aftersun lotion

Very helpful, thanks for the answer!

Hey, I need some help with this classic set. Bought this set used and my question is can I solder these two red wires together demonstrated in the picture? At the moment the red wires that connect together from the pickups and then are supposed to continue to the battery - are separated. In the schematic the black thing holds these red wires together. Easiest way would be just to solder dem red wires together. Any advise? Thanks
