In order to wire the Derale 26" Dual High-Output, Electric Radiator Fan-and-Shroud Assembly part # D16927 to a manual switch you will need two of the Derale Lighted On/Off Switch for Electric Fans part # D16740. There are three terminals on the switch which are for accessory, power, and ground. The accessory terminal will need to be attached to the yellow wire on the included relay harness. The power terminal will need to be attached directly to the positive battery post and the ground terminal will need to be grounded to a clean metal surface.
I have attached a photo of the wiring diagram for you but it is also included in the instructions manual.
