You can use the exisiting wiring to trigger the relay
As dave says, new wiring from the battery, relay etc it will be fine.
My turbo cab has twin fans, my pal re wired it with a relay, seperte fuse box, optional over ride switch. It's all good.
My standard fan switch will soon be done away with as my ecu will control the fan
