ERROR 7 - WHEEL # 1 (LOWEST WHEEL) HOME POSITION SENSOR
If you have Error 7-10, the problem is associated with the physical sensor itself. Check to make sure it is aligned properly and plugged in. Check to make sure you have 5 volts going to the sensor between the brown and the black wire - during the check, block the sensor with your finger - if you see a voltage drop, the sensor is good. If not, the sensor is defective. I think in your case, as long as the game starts and initializes properly, the problem is most likely just an alignment issue.
