About this part
Repair those old connectors commonly found on BMW E30, E36, and E46 vehicles with loose terminals. The rubber overmolding on the terminals tends to disintegrate which can cause them to fall out of the housing or not make a good connection.
This replacement terminal shell is designed as two pieces and fits tightly over the terminal after the old overmolding is stripped off. Apply a small amount of silicone RTV to the terminal first to glue the shell in place and make the connection waterproof.
Print both pieces vertically to ensure that they are perfectly circular.
