of the cables 26 34 are pulled upwardly and toward the fairleads 18 22 thereby raising first and second mud flaps 14 16 to lower the mud flaps 14 16 the switch is placed into a second position which causes the motor 202 to rotate the motor shaft 204 in a second direction opposing the first direction upon rotation of the motor shaft 204 in the second direction the first and second sheaves 205 206 are also caused to rotate in the second direction to uncoil the cables 26 34 from the coil on the sheaves 205 206 in this way the cables are uncoiled thereby allowing the mud flaps 14 16 to be lowered in another embodiment motor 202 is also electrically coupled to a reverse light and or a reverse audio alarm of the vehicle that way when the truck transmission is put in reverse the motor 202 is automatically activated to rotate the shaft 204 in the first direction to raise the mud flaps 14 16 when the truck transmission is move out of reverse the motor is activated to rotate the shaft 204 in the second direction to lower the mud flaps 14 16 in yet another embodiment the mother motor 202 is also electrically coupled to a reverse light and or a reverse audio alarm of the vehicle and a switch in the cab of the vehicle in this embodiment when the truck transmission is put in reverse the motor.
