This is the same ECU harness supplied with the AiM EVO4 data logger. It has a 5-pin "712" (metal screw-in) connector at one end and 5 un-terminated wires at the other end. The wires are labelled RS232RX, RS232TX, CAN+, CAN-, and GND. It can be used to wire your EVO4 to an ECU using RS232 or CAN protocols. This includes most racing-only ECUs and some OEM ECUs.
Note This cable gets plugged into the "ECU" port of the EVO4 (not the "Exp" port).
For use with AiM EVO4 data logger only. Not for use with any other AiM device. The wiring on the 5-pin 712 connector is not the same as the CAN ("Exp") port wiring.
