I just installed a new built tranny and a yank 3800 converter and at the same time I installed a hayden 30,000lb trans cooler with its own fan. I mounted the cooler with the fan on it dope style. I am wondering whats the best way to wire in the fan? I have seen where some people wired it to the cooling fan relay. will that work and if so which one ?

 

Come on some one has to have some input on this.
