This is an original handmade product. It is an engine grounding cable for Subaru Sambar TT/TV/TW, a genuine replacement type. The conductor thickness is 5.5mm2. It is wired so that the engine head cover and the wheelhouse reach the ground point in the shortest distance. It is thought to be useful for refreshing performance. Please use it at the buyer's own risk. We cannot provide support after purchase (such as instructions on how to replace it), nor can we accept returns or refunds after shipping. We look forward to your purchase if you understand the above.
