This product prevents the wiring from coiling around when adjustaing the ride height upon set-up without the need to disconnect the EDFC motor kit. Depending upon driving condition and/or settings, the EDFC motor may rotate in one direction. If left alone, the wiring might get tangled up with piston rod and, consequently, might be broken or disconnected. It usually doesn not create any problem if the wiring is unwound whenever the tangling is found or upon periodic inspections. However in rare cases the incidence is quite high enough to cause breakage or disconnection in between routine maintenance. If tangling of the wiring occurs within a few day of EDFC installation, install this product to prevent future occurrrence.
