I'd presume the 5th wire has to do with the light on the handle. Maybe you could identify which wire is for the light by leaving the original cable attached, disconnecting one wire at a time, then seeing if the light still works(?). (My guess is one of the two smaller wires. Although you'd have to be careful... more than one wire could deactivate the light but not be EXCLUSIVELY for the light.)
As for matching the other wires, edk-Austin seems right. But did the new cable not come any kind of wiring diagram or wire color description?
