(61131378418) - Terminal Plug Housing (grey) (2 pole) - E30, E39, E32 (see details) (Genuine BMW) (4 available)

BMW part number 61131378418 (61-13-1-378-418) is a 2-pin, right-angle grey plastic electrical plug housing. It serves as the grey-keyed counterpart to the white 61131378417 connector shell, fitting various BMW 3 Series (E30), 5 Series (E39), and 7 Series (E32) models between 1982 and 2003. 

What It Does & How It Differs

• Color-Coded Keying. BMW produced this 2-pin housing family in three colors—white (...417), grey (...418), and yellow (...419). Each color has slightly different plastic alignment tabs (keyways) so mechanics cannot accidentally plug the wrong harness into the wrong sensor.
• Common Applications. Like the white version, this grey housing protects two metal wire terminals on exterior and engine-bay sensors, including windshield/headlamp washer fluid level sensors and rear differential speed sensors. 
• Shell Only. The part includes only the empty grey plastic connector body; metal pin terminals and rubber weather seals are purchased separately.

Compatible Models & Years

• 3 Series (E30, 1982–1994). Fits 318i, 318is, 325e, 325es, 325i, 325is, 325iX, and M3.
• 5 Series (E39, 1995–2003). Fits 525i, 528i, 530i, 540i, and M5.
• 7 Series (E32, 1988–1994). Used on models like the 750i/750iL for intensive windshield and headlamp cleaning systems

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.
