Hey guys just a quick question I pulled out the thermostat and switch out of an old heater to use in a incubator I'm making
Having trouble working out where to connect it all and where the colour co-ordination comes in?

Sorry, but we cannot make heads or tails of how that unit is wired just by photos.

We also cannot tell if the unit you show is rated for the voltage and amperage the incubator will need.

Would be simpler if you purchased a proper thermostat for your project.
