Dual electric fans, FIRE!

I mean draw the hot from the starter large bolt to get my 12v due to my battery being in trunk. Now I tried to rob power from my dash lights to power the switch however that blew out my dash lights. So I am thinking of going double hot to relay and use the toggle for ground I just found this online, Im a bit worried keeping it hot and relying on the switch to gound it but whats your thoughts, look at the link I posted

I'm starting to get the idea that you are not reading what some of us are posting. I already told you how to hook it up, and it's exactly like your diagram, except the coil terminals are reversed.

WHY are you going down to the starter? Do you NOT have a starter relay?

On the dash lights-- worst possible choice. are you not aware that your dash lights go THROUGH THE DIMMER control on the headlight switch?

Personal choice, I don't like the idea of fans running / key off. I would pull power from, say, the radio plug. It has two wires, one is the dash light for the radio, the other is "switched" from the key.
