If you're experiencing hard starting, flaky charging, or other electrical issues, your engine ground strap may be the culprit. On older BMWs, the engine ground strap is a thin, non-insulated cable that spans from the engine mount arm to the frame horn. Despite the seemingly simple nature of this part, on older cars, it is known to cause massive headaches. Due to its non-insulated design, years of exposure to water, dirt, and road salt will cause the wire to corrode, ultimately leading to complete failure. A break in this cable will cause an open circuit, resulting in issues with the vehicle's electrical system and potentially leading to a no-start condition.

To solve this issue, ECS has engineered an exact-fit, upgraded ground strap for your BMW! Unlike its OEM counterpart, this design features insulated, large-gauge copper wire for dependable conductivity and long-lasting durability. Additionally, factory-style lugs are zinc-coated, crimped, and soldered, ensuring protection against corrosion and oxidation.

Whether you're replacing a visibly corroded strap or proactively preventing failure, this solution from ECS is sure to provide lasting performance and protection.

FEATURES

Direct-fit replacement and upgrade for E30 (318i/is), E36, E39, E46, and others Solves intermittent grounding issues caused by aging OEM straps Clean, stealthy design that fits seamlessly in factory engine bays Factory length and lug orientation for drop-in fitment 2 AWG tinned copper cable for excellent conductivity and corrosion resistance Zinc-coated lugs, crimped and soldered to resist moisture and oxidation Black UL1015-grade insulation withstands oil, heat, and abrasion Discreet ECS label for a clean, OEM+ look Replaces OEM part numbers 12421737755 and 12421714262.

Brake pad wear sensors are a convenient part of the braking system, notifying the driver of when the material on the brake pads are getting low and need to be serviced. Unfortunately it is common in custom or upgraded braking systems that the pad wear sensor is non-existent or does not mate properly with the connector on your vehicle, leaving you with a brake pad wear warning every time you start your vehicle.

ECS Tuning has developed this direct-fit Brake Pad Wear Sensor Bypass to alleviate this issue. This sensor bypass will trick the vehicle's electronics into thinking that the brake pads have adequate pad material to keep the dashboard warning from appearing. No more unnecessary warnings when installing a big brake kit or your own custom setup. This bypass is a plug-and-play component that requires no modifications so you can revert back to your OEM setup if necessary.

Some vehicles may be equipped with two front brake pad wear sensors, or a front and rear sensor, please be sure to double check the required quantity for your vehicle before placing an order.

*During installation, make sure to clean the mated female connector on your vehicle of any dirt or debris to ensure that the Brake Pad Wear Sensor Bypass is engaged securely.
