Relays for pump and Fan

I want to redo some wiring and install relays for the pump and fan. Whats the most cost effective way to go for installing for the pump and fan?


Thanks Tore

These work great for that. 40 amps and comes with the female plug and wires for 10$.

Del city is where I buy all my wiring stuff from, their prices are hard to beat

Thanks to all who answered.

something else, I used a SPAL temp sensor to trigger the relay. It works well, and turns the fan on only when it is required.
