This is the same DC power cord supllied with the AiM Solo. The Solo has a strong on-board battery, but many people like to run it from the vehicle's 12-volt system. The 3-pin connector screws into the bottom port on the Solo. A cigarette lighter plug is provided on the other end to fit your vehicle's standard 12V power port.
Not for use with SoloDL. The SoloDL has a 7-pin CAN plug, so it uses a different 7-Pin to DC Lighter Plug Power Cable for SoloDL (Part No. MC-575).
