Cable conector

Cable conector for 2.2 mm electric wire
You have to peel 10 mm of each end you want to connect and: 1- bend to inside one the female part and, 2- bend back outside on de male part, the alternate position on the 2 and 3 wires makes very difficult to short circuit at the coupling time,
I been using this on a 125cc pit bike engine to connect to battery and cdi etc. no problems
