This harness connects your SoloDL to your ECU via CAN or RS232 wiring. One end has a 7-pin 712 (screw-in) connector to fit the SoloDL, and the other has 6 non-terminated wires (CAN+, CAN-, RS232RX, RS232TX, Power, and Ground).
This is the same cable supplied with the AiM SoloDL for CAN / RS232 Connection (Part No. MC-572).
Note: For SoloDL only, not for Solo.
