I can trigger it manually so the wire all the back to the fan, relay and the fan itself works. |

The factory fan switch doesn't close until 235F which is damn close to the "red zone".
The fan will also come on when you turn on the A/C.
My GT has no A/C, so the only time my fan came on was in stop-n-go traffic on a really hot day close to "the red". 
I replaced it with a 210F/200F switch (for 195F thermostat) which keeps engine temps more consistent.

PS - I have the VSS gear from the car you got the hood from.[This message has been edited by fierosound (edited 06-25-2020).]

No A/C on this GT either. I bought the lower temperature switch as well as I wasn't really comfortable waiting until the red zone either.

The fan won't come on often if you're driving and car is moving.
With the 235F switch I never heard the fan for the first 2 years - until I was stuck in traffic because of an accident in Kelowna at 29C. 
I wired in a manual toggle switch to ground the circuit and later installed the 210F/200F fan switch to do the job.
If fan isn't on after passing mid-point on gauge, switch may be bad (gauge not that accurate to start with).
Leave hood open and idle engine while monitoring gauge and wait it out until fan kicks in.

With the manual switch what is the best path for the wires. Not too many places to poke wires through. I was thinking of pushing the wires from the engine (switch) into the cab but it looks almost easier to do from the front (replay).

I haven't used the manual switch since I installed the 210F/200F fan switch.
But it's nice to know it's there if the fan switch ever craps out.
The wiring already runs through the car.
C100 is the firewall connector right above the gas pedal.
Tap into the Dark Green/White stripe wire with a switch to ground.

Thank you! Wired in a fan switch over ride. Car is now plated and insured. New tires booked for tomorrow. Just need to speed sensor wheel gear.

I said I had a VSS gear from the same car you got the hood from.
Contact me through www.CalgaryFieros.com and you can come pick it up.
