Attend the sufficient profile section (at least 10 mm2), the suitable fuse rating and the conductivity of the cables when you purchase your wiring kit. Clean and remove ruststreaked and oxidized areas on the contact points of the battery and the ground connection. Make sure that all screws are fixed tight after the installation, because loosely connections may cause malfunctions, unsufficient power supply or interferences.
