I bought a electric fan and a wiring kit with a relay and 185* thermo switch,
however, I have no place to install the temp switch. I am thinking about just hooking it up to a keyed fuse. I know the fan will be on as long as the key is on but I do live In AZ so I don't think it will hurt.

Is there another option that is clean and functional.

thanks

The whole point of an electric fan is that it only runs when you need it. Does it use a sender type switch that screws in like for the gauges?

MonsterBilly

yes that is the type of switch it uses.

I had to switch to the electric fan because I switched to a serpentine set up and do not have enough room between it and the aftermarket radiator to fit a conventional fan. So I had to switch to a front mount push style electric fan.
And since I frequently drive the car on 100* plus days I was thinking that it always being on would not be an issue.

Well, puller fans tend to work better, so hopefully you won't have issues in extreme heat. Are the intake bungs full? What about the thermostat housing? If you don't have one, you can get a thermostat housing with a threaded bung for senders, and just install the switch there.

does anybody know of a sending unit with a switch where I can use it to work a gauge and a switch to run a fan

I'm not sure if such a beast exists.

That's handled by EFI though, the temp sender tells the temp, and the ECU just reads the temp info to power a relay. In that case the ECU is an external unit that controls the fan.

To have a sender that did both, you'd need a sender with a built in switch at a set point. I've never seen one.

Jegs has a thermo switch that runs fan preset at 185 on 175 off that's what I have with a manual over ride switch on dash I can use at any time

If all ports are full buy a t fitting that will handle 2 items

A tee isn't a good idea for a temp sensor. The fluid in the tee will pocket there rather than circulating, and you'll get inaccurate temp readings.
