Fan overide.

This is understood.
My concern with this setup was the need to use a diode, so you did not fry the computer.
"Fire her up and she blows..." only if you turn on the switch, right?

Yes it works only when the switch is on
there is no juice going to the pooter the green wire I tapped onto goes directly back to the relay I do not beleive it goes to the pooter at all
this is what I have read everyone else with late models has done

great!

thanks!

I will get on it tomorrow...

I see no need for a diode

I abandoned the fan relay in the power distr box I tried that route but kept blowing fuses and turning my ac clutch on it does weird things forget it
It took me all of 30 min

I wonder if this is due to supplying power to a ground activated circuit. ( a question I was trying to get the answer to.)

 

[XJ4PLAY]

Well, installed and working.
Took me about an hour and fifteen minutes, but that was due to me running the wire in the factory wire looms where possible and adding my own where needed.
Actual wiring was simple and straight forward and only took about half hour as stated.

Thank you all for the input.

 

[MrMom]

Good deal glad we both benefited here
stay "cool"!

As a last resort, I did this mod last night and the following set of instructions were very helpful. It worked just how it should the first time. So, thank you!

Ok got the fan on
here is what I did 12v trigger lead from the fuse block( on the ign side so it only powers up when the key is in the start position) to a toggle switch then to the # 86 terminal on the relay I added for the circuit(this 12v lead opens the relay to let juice go to the fan)
ground wire from the relay # 85 to the body
10 guage hot/load lead fused from the battery to the #30 lead on relay( this is the main power to the fan)
14 guage supply from the # 87 term on relay to the green factory wire to fan located at a male female plug junction near the radiator cap justed crimp spliced into it.
cranked her up and she blows
I beleive this is what you need to do
