(61131378417) - Terminal Plug Housing (white) (2 pole) - E30/E36, E34/E39, E32/E38/E31, Z3 (see details) (Genuine BMW) (5 available)

BMW part number 61131378417 (61-13-1-378-417) is a 2-pin, right-angle white plastic electrical plug housing. It serves as a protective connector shell for chassis wiring terminals, most notably on the rear differential (final drive) speed sensor. 

What It Does

• Protects Electrical Terminals. It houses two metal wire terminals in a right-angle orientation, locking them securely onto a sensor or switch while shielding the connection from moisture and road grime.
• Primary Application. It is most commonly used on the rear differential cover to connect the vehicle speed sensor (trigger contact) to the main wiring harness.
• Important Note. This part number is strictly the empty plastic connector shell—metal pin terminals, rubber wire seals, and protective boots are sold separately.

Color-Coded 2-Pin Sensor Housings - for BMW E30 models (84-93) - BMW used color-coded alignment tabs (keyways) on these 90-degree plastic shells so mechanics would not cross-connect adjacent wiring harnesses. All four variants are used across US E30 models (318i, 318is, 325e, 325es, 325i, 325is, 325iX, and M3).  The "408's" are sold out...I have the other 4 in stock.

• Black (61131378416 / 61131378408). Used for the rear differential speed sensor, late-model horns, and washer fluid pumps. 
• White (61131378417). Used on the rear differential speed sensor (depending on production year) and coolant/washer level switches. 
• Grey (61131378418). Used for fog lights, headlight/intensive washer pumps, and fluid level sensors. 
• Yellow (61131378419). Exclusively keyed for the on-board computer (OBC) ambient exterior temperature sensor located in the front brake cooling duct.
