HKS fan controller

[Shadow]

I have an HKS fan controller wired in to my 1JZ but not yet to my Fal electric fans. The instructions say to connect the last wire (grey) to the fan computer. I was not aware of any fan computer in the 1JZ or even the 7M. Please any help. Thanks. :wtf:

The stock 1jz has a computer solely for the purpose of driving the stock hydro fan. I am 99% sure that is what the directions are referring to. Wish I could help, but I don't have the hydro, I went with the 2jz setup. Good luck man.
