aRacer 2 to 5 (AKA 1 to 5) cable splitter allows you to expand one ECU port to 5, so that the ECU could be linked with sensor modules, such as iMode Gen III control module, etc.
The aRacer 1 to 5 cable splitter allows you to adapt and use optional aRacer modules and accessories to your aRacer ECU. This splitter harness will work for most aRacer ECU that has the ECU port connector/s.
