These are the plain beige ABS plastic non-latching connectors and 2.8mm (0.110") plain brass automotive crimp terminals that have been used on Japanese sport bikes, touring bikes, and dirt bikes since the late 1970s.
Includes 2.8mm latching connectors and terminals found in many Japanese motorsport applications from the late 1970s through to the mid-1980s. More common in automotive applications, but can also be found on some motorcycles and other Japanese equipment. Though possible, it's not advised to interface our latching and non-latching 2.8mm connectors. Does not include a Ratcheting Crimping Tool.
