I have a remote MotorGuide Lazer II 24 volt 62 lb. Thrust trolling motor.  I want to change motors to a manual MotorGuide Beast 775 with a 65 lb. Thrust.  It has a 24/36 volt system.  The Beast 775 has a blue and white wire that connects to the chip board and the Lazer II has a blue wire but I have no idea where it goes.  Can someone help me with directions to change out the 2 motors and where the wires go to.
