BMW E30 Connector Plug for 2 Speed Radiator Fan Temperature Sensor 1378412 DetailsUp for sale is a 90 degree style connector that plugs into the radiator sensor/switch on the BMW E30. This connector is nla from BMW so we developed this aftermarket alternative made from a high quality temperature resistant nylon. The three internal wire terminals are original BMW Parts. This part will not work for the auxiliary fan power connector as the wires are much too thin for the application. You can purchase just the housing (without the wires) for this application which can be found here: https://www.ebay.com/itm/167041570651 This will plug into the slots where the straight 180 degree connector (61131378410) is used. However the buyer is responsible for the fitment since the wires exit at a different point and may interfere with the surrounding objects. I personally verified that this connector will work on late model BMW E30 front turn signal lights.
