Car Stereo

I need to know if i am doing this right. yellow goes to batterey. black is ground. red is acc. where do connect this to. i am rewiring the whole system there is no wiring left so i need to know exact details where to locate these wires or where to wire them into fuses. thanks for your help

Your red wire can be routed to your fuse panel, just use a test light to find the wire that only has power when the key is on. if you plan on running your constant (yellow) directly to the battery, make sure you have an inline fuse, car fires are only cool if its not your car.
