12v Switched near Radiator

All,

I'm going to have my FiTech provide the switching of the Fans. It has internal parameters to set the hi/lo limits. It sends a ground signal to the Relay at terminal 86. It has a temp sensor installed in my AirGap. I will run a lead from the Brn/Blu Ign to trigger the relay. I'm also using a relay to power the FiTech also but it will be on the firewall. Under the battery will be just fine. If it helps I do have a new Acid Mat going in under the battery and the tray! I trying to keep my Bay as clean as possible and still serviceable.

Thanks,
Marion
