The MyChron3 XG-Log Dash (Part No. MC-230) can be connected to many different ECUs via RS232 with the addition of this harness. Note that some ECUs connect via CAN and require the use of the CAN Harness for XG-Log (Part No. MC-316) instead.
We also offer the RPM Harness for XG-Log (Part No. MC-313) for use without an ECU.
