HI

Could anybody tell me what colour are this PU's connecting wires? I just bought one and its wires are red and black. Is this correct? I just wanna make sure that it isn't a fake.
The label or sticker on the bottom says: ROHS-IZD37 ; and the second row: SJB-2N 20080226. The cover is real for sure. The coil or magnet wire is covered with a black cloth tape.
Thanks.
