I'm not sure how your 1986 Oldsmobile Cutlass is setup but the Derale 40/60-Amp Dual Relay Wiring Harness for Dual Fan Assembly # D16765 that you referenced is a great option if your electric fans, including one on a remote, fan-mounted cooler, draw more than 10 amps of power. These help to protect the electrical system on your vehicle.
