Does anyone know where I can find battery cables I need

What is your question?

My husband truck has the same problem, but It has not power windows, anti thief device, or any type of power assist. He turn the key and nothing then goes out and plays with the cable on the battery and most of the time it will start. His problem started over the summer and is still happening. He does not wash his truck a lot either. Tried to buy new cables but having trouble finding them. He also has a different kind of set up. His one cable goes into a fuse box then comes out and goes to starter I believe. So if anyone can help with that thanks. His cables have no build up on them either.
