Will switch NEGATIVE power wire of 13-ampere automotive radiator fan. Long strings of words are confusing. Does a diagram exist to do this? I don't need heatsink advice merely a diagram or schematic to wire a circuit board with correct resistor values and correct capacitor values. I assume a single 470Ω would be enough to bias input of 12 volt signal for the opto coupler.
