Help with an electrical issue (OT)

[Jim Roach]

Here is my problem. I have a small motorcycle bluetooth unit that I am trying to wire up. Seems simple enough except for an electrical illiterate like me. It has 4 wires- White-remote control antenna, Red-ACC power, Black-negative. Now this is where I have the problem. The last wire is yellow with an inline fuse and is listed as positive+. If the red wire is power how can the yellow be positive? Any help will be greatly appreciated.

typically for stereos one + is for switched power and the other(usually yellow) is for constant power to keep the memory going

Ok, now I understand. See I knew it would be simple. Thanks Young Ed.
