I have only just got this fan to replace my 3 speed, also i have yet to test it while off the car am at moment charging a spare battery to do this but need to find which wires i use this is what is inside the black box.
Black & Red wire to motor
Red to a Brown which goes no where ?
then we have this spaghetti
Where do i start as you can see two black wires are not in use and have been cut also the little thin wires Green/Yellow and thin green
Do i need to hook up the red and black coming from the motor to the battery terminals ?
