You’ll have to snap the new grummet tight in this stage and install it. Ensure the grummet is installed securely.

Step 5: Close the Control Box

Screw the control box and close it carefully using the 4 bolts you unscrew in step 1. Now secure the spot lock cable/wire to the trolling motor using the zip ties. Also, you’ll have to cut the additional wire off. 

Step 6: Go to the Center Housing

Press the center housing (both sides) and lift it. It will open and detach. Disconnect the wiring white and black and lose the strain relief cables. The white and black wiring is at the motor’s base point.

Step 7: Place the Spot-Lock Steering Cable

Place the steering cables of the spot-lock and tighten the strain relief. Use a screwdriver to tighten it. Ensure the line is sliding through the hole smoothly.

Step 8: Connect the Power Connectors

Now connect the spot-lock power connector (white and black wire) and the trolling motor’s power cable.
