SB connectors come in four different amperage ratings (50,120, 175 and 350) and six colors (Yellow, Orange, Red, Gray, Blue andGreen). Connector kits are also available containing one housing andtwo contacts.

NOTE: Connectors will only connect to anotherconnector with the same amp ratings as well (example: a gray 50 ampconnector will only plug into another grey 50 amp connector)
