New switch for electric fan set-up.(Pictures)

So, had an early day at work today, and decided to finally hard-wire my electric fan switch in, to where it looks stock-ish.

Would have taken a few more/better pics, but some heavy rain clouds were rolling in, so time was of the essence.

Here was the switch before.. great switch, had it on my old tundra for a couple years. Was just temped-wired in here, laying on the ground. Had to change that.


Ideally, I'd like to have a push-button switch that looks like it came that way from the factory, but I couldn't find any with any type of "fan" picture on it.
So, I took a basic single pole, single throw 15 amp metal switch I had laying around, and used that with one of the stock dummy-inserts.




Fished two wires up through the firewall. Already had the other fan wires still in, so this was a piece of cake.. Just taped the new wires on the old, and pulled on through.



Next, pulled this section of the dash up.


Wired 12v directly to the switch, and the exit pole, wired to the relay.
(More heat-shrink)


Next, I hooked up a basic 4-pole, 30amp relay, and wired the switch to the coils, then the electric fan to the load.. and a little heat-shrink for good measure.


Final product:



Next project, get a hold of a good, insulated buss-bar to setup a remot power-tap. Tired of the octopi-battery:

 

No thermal switch?

 

Nah. I've got one I could wire up. Once I teach my Fiance to drive a stick, I'll probably put it in. She always remembered to flick on the switch in the tundra, so I'm not worried.

I just turn it on when I start the truck up, and leave it on until I'm on open freeway. Don't really trust the thermal switches, have had too-many aftermarket ones(see flex-a-lite) fail. Been running all my electric fans like this for the last 10 years, and it's never let me down. I always keep an extra emergency switch, and relay in the truck, just in case.

 

OP, did you ditch the clutch fan or piggyback a electric one in? and do you have pics of the fan you put in and cfm's?

thanks

yeah. i wouldnt run like this at all.... you do realize that the temp gauge on the truck literally moves none between 175-210*f coolant temps right. its only around 215-220 that it starts to move from its normal position.

There is a reason why electric fans are not found on any trucks, they fail leaving you screwed. Worst case that happens with a viscous clutch fan is it sticks always on.

 

True.

I have had a efan on my other truck since 2006. Flexolight black tragic 180.

Been running strong since never a hiccup. Used the crap flexalight controller for a while then went to custom tune to run my efan like factory.

Yes using factory wiring since my truck came factory with a clutch fan and an electric fan.

 

Very true. If it fails, I could be screwed. Have yet to be, though.
*knocks on wood*
Definitely jinxing myself now that I said that, lol.

I've been running electric fans in all of my trucks(and cars, for that matter) since my first vehicle. I full and well understand the risks involved, but you know what? Gonna take it and run.

I appreciate your input though

 

I'll get some pics posted up.
Ditched the stock, and running electric only.
Per manufacturer website, it's rated for 3,300 cfms.

My old 96' Tacoma, which I sold to my little brother, has had the same electric fan (flex a lite black magic) since 2007. The switches wear out faster than the fan does lol
