    First - What is the primary source of control for this fan? Do you have a temp probe or some other automatic means of controlling the fan, or is the toggle switch going to be the primary? If so, what are you using for a temp guage? Is it accurate enough?


    Anyhow, back to the switch, relay, and in line fuse (all three of which you will need). These are all pretty universal installs, so a search of google will yield some detailed DIY guides with photos and such. Start with this about relays -

    I'm gonna use the temp gauge as for heat and its gonna be the primary for turning it on and off

    Ill read up about it to see to configure it some how haha

    really this is not hard at all to set up. you get a single throw relay that reacts to 12vdc power.

    find a stable power source in your dash to hook the rocker switch up to.

    ground the rocker to likely your chassis. run the output of the rocker to the input for the relay throw.

    ground the throw of the relay to your chassis.

    break the power line of the fan and insert the relay pass through into the break in the power line.

    done.

    Also, Ive heard in setups such as what the OP wants to do, when the power is cut to the fan the fan becomes a generator until it stops spinning. This over time will kill the relay.... So a diode should be place between the fan and relay.

    Thoughts folks?

    most GOOD relays come with a built in diode. In fact do not buy any relay that does not.
