The volume can be adjusted steplessly from approximately 3 seconds to approximately 16 seconds. It works simply by replacing it with the genuine product. Confirmed to work with Daihatsu and Suzuki. It should work with other manufacturers if the connector fits. When installing the adjustment volume, it is necessary to drill a hole. If you don't want to drill a hole, you can also attach it with double-sided tape. The cable is about 80cm long, so you can install it wherever you like. The cable has crimp terminals in the middle, so it can be separated. There is no polarity, so it will work regardless of which way you connect it. The adjustment volume knob is not included, so please prepare your own. (I use a suitable cap - see photo 4) #Daihatsu #Suzuki #Toyota #Nissan #Mazda #Subaru #Intermittent #Wiper
