Hmmm, I wonder who's car that is then. They're old pics, and the engine bay is gray. Looks like a cruise wire in the pic. Oh well, the process is the same for installing fan relays. Tap into the ignition-on wire for the alternator harness using a tinnerman splice. Connect to the main battery feed on the alternator, and connect to the fan switch. And a ground wire. No real need for fusing, if the fan shorts out in an accident and happens to be active, either the relays will pop, or hopefully the 80A alternator fusible link will blow. But the fans don't run all the time anyways. And you'll likely turn off the key to cut power to the fans.
