Ground Cable - E30, E36, E46, E34, E39, E32, E31, Z4, Z4M

This part is listed by BMW as BMW part number 12421737755 (12 42 1 737 755) and is described as Genuine BMW Ground Cable / Earth Strap for many BMW models. It measures 380mm / 15 inches in length. Often referred to as a ground strap, it connects from the negative battery cable to the chassis of the car. Over time, this cable corrodes and breaks down, interrupting the electrical flow of the car. A bad ground cable will eventually cause electrical problems on your BMW. 

This ground strap / earth cable fits a variety of BMW models including: E30 318i / 318is / 318ic (1989-1993 with 16 valve engine), E36 3 Series 1992-1999 (all), E46 3 Series 1999-2006 (all), E32 7 Series 1988-1994 (all), E34 5 series 1989-1995 (all except M5), E38 7 Series 1995-2001 (all), E39 5 series 1997-2003 (all except M5), E31 8 Series 1989-1999 (all), and E85 Z4 with M54 or S54 engines. 

This ground cable is a Genuine BMW part, so you can be assured it's the best quality and fitment and will last a long time, just like your original one did.
