Your new Kooler comes with all the hardware needed for install. Please see the photos for typical motor tab placement. Some motors will need to be rotated. Tekno owners use the 4 m3 x 16 cs screws and the 4 lock nuts to mount the fan. The remain 2 screws are to mount the Kooler to the car. All other mounts you have the option to use 2 or 4 screws to hold the fan on. I see most people with just the 2 top screws. There are 2 m3 x16 button head and 2 washers to hold the Kooler the the center diff mount.
If you install your esc in the rear all wires will need to be shortened. If esc is kept in standard location the battery wires may need to be lengthened. Either way installation is very simple each mount is custom fit to your car.
If trimming is needed your hobby knife will work perfect.
