Hello, I purchased a boat recently that looks to be wired for a helix 7 according to the sticker on the chords. It has an ultrex trolling motor on it. Would I be able to just purchase the unit and plug and play. Below is the two connections on the boat.

The power cord works with any number series and Helix units. Some older ones also.

If the trolling motor has a MDI or MSI transducer and the 7-pin plug is what is attached to it, then it has to be the correct version to work with a Helix 7. I have the adapter for the larger units and it has 7 pins and is the MKR-MI-1 and it won't work with a Helix 7.
You would need the MKR-MDI-2 cable for a second or third generation Helix 7 Down Imaging unit.

Compatible units and the adapters are on the Minnkota website------
