Once had a CX500E which I fitted a manual override to. Two up with luggage going uphill tended to raise the temperature and the fan didn't kick in early enough for me. I simply traced the two wires back to the tank and soldered two flying leads to them. To these I crimped Lucas connectors and a hold to run push switch. I originally had a rocker but kept leaving it on. The push button if held in as soon as the temperature started to rise only needed held on for ten seconds. You need to source a fairly robust switch as the cooling fan pulls 7.5 amps.
Never underestimate the ingenuity of an idiot!
