If you look closely at this version the #30 terminals on relays #1 and #2 are fused to the battery so they are hot all the time. The fans + lead is connected to terminal 87a on relays #1 and #2 so they will always be on because current flows between terminal 30 and 87a when the relay is off.

Bah you are correct. Fixed. I had to add another relay, move some things around. This one should work, though. Thanks for your troubleshooting
So are those relays in the diagram on the fan controllers? How much wire needs to be run and what are some good switches with maybe a green or blue light? Also whats the purpose of putting them on switches, So that you can still turn them on if the controller breaks? Excuse my ignorance

I'm not 100% what comes with the Troyer kit since I have not received mine, but I know from looking at various installation instructions that it comes with at least a couple relays (one for each fan) which is most likely turned on by the use of the thermistor. I made Therm1 and Therm2 a "black box" item.. meaning that I don't know what's in it, but I know it must have at least those connections.
As for the wire, the most wire you would need is 3 maybe 16 or 18ga wire from the cab into the engine compartment. Then you may need some additional wiring to connect up the new relays to the basic setup... but you may be able to take advantage of "extra" that come with the kit... if it actually does come with extra wire.
Reason? Some people have the desire to turn them off. I did it for purely academic reasons... so I'll put them in, but I don't know if I'll actually ever use them. I think it's a good plan to have incase the controllers fail, but some people have mentioned turning off the fans while offroading. I think it's just a cool idea to design a circuit and have extra switches in the cab
kuruption if you like to have things in the cab lights n stuff here is something i have been playing with mainly to try and help a guy that asked a question and secondly to show others that said it couldnt be done that it can .sorry my drawings are not as sofisticated as the high class computer aided ones that you have i cant figure out how to use the edit program i downloaded lol. e-fan monitor lights

Hey,
I think you may be making it more complicated than necessary. There is a dimmer wire at the back of the radio (blue/red on the 2004-2008 models) that is a variable voltage lead meant to be connected to the radio. You should be able to just tap into that and use a relay to switch the LED on or off as you have it. Something like this comes to mind:
Of course, you would need to add any necessary resistor. And just as you showed, you can hook an "off" LED on the 87a terminal the same way the ones in the diagram are hooked up.
Wouldn't this work? I don't understand the requirement to get power turn on from the parking lights?
I just noticed this; If you look at the blue Wire coming from the two controllers to the relays. What is stopping Controller #2 from turning on fan #1 when it activates fan #2?
FWIW I use the 4 strand flat wire that you get for wiring trailers. They have 4 different colours so it makes it easy to trace circuits. It has been a while so I have forgotten what wires cami in my Troyer kit. It did have 2 controllers and they each use a relay. There were no spare relays in my kit.

Under normal running conditions, Controller #2 would be set at the higher temperature... so that would mean Fan #1 would already be on.
When the thermistors are bypassed, this is all controlled by the in-cab switches.
As least, that's the idea. Small addition of a diode fixes this, so I updated the diagram.

Drawn like you have here the indicating LED's would only work with the lights on. Other relay with the park lights used as a trigger so they will work at full bright during the day with the lights off.

yes it will if the dimmer wire going to radio has power going to it when the lights are off that is basically how i had my first diagram drawn up but a member "4rd4life" pointed out to me that the leds would not work when the dash lights were off which is why i added the other relay to control between the power comming from the dimmer and an ignition controled power so that when the parking lights were on or off the led lights to monitor the fans would always have power. and the power to the parking lights controls the relay as to where the leds would get there power from.

Ah hah... okay that makes sense Here's the updated. Just so everyone knows, I'm not taking credit for this one, this was designed by jrfonte with inspiration from 4rd4life.
that looks alot better than the hand drawn diagram that i made and scanned to the computer lol. i still cant figure out how to make the software drawing program thing i downloaded work i cant even get it to make a square and stay on the page lol. i guess software just isnt my thing. thanks for taking the time to clean it up for me kuruption.
Got my delivery today and took a look at the wiring schematics. The Troyer relays are ground switched, so I modified the diagram to reflect a ground-switched setup.
