This interface is designed to solve the problem of irregular and weak speed signals. In today’s modern vehicles it is not always advisable to just simply connect on to a speed signal wire. The speed pulse wire may be too weak or can be too heavily charged, which can cause problems with speedo’s not functioning correctly or EMS warning lights being activated. Using the DI 104 interface can help eradicate these problems. The interface also has a built in frequency divider (divided by 4) and can be used on 12 volt and 24 volt vehicles.
