Whilst unpacking a recent delivery of an bike with throttle my wife inadvertently cut through the throttle cable. I now need to rejoin the two ends. The outer cable has 3 small insulated wires within (red, white and black). The guy at Maplin said I could join the two cable ends together in a single crimp. Being rather ignorant on such matters I thought I would check on here if that was ok. To the uneducated it seems odd to have 3 separately insulated wires all joined together (in a single crimp) where they connect up with the other end of the cable. Thanks in advance for advice you can give.
