Need help with manual fan switch >
hey guys
all I want to do at this point is wire up a switch that will turn on the main fan at will
..
what would I need to do to do that alone??
I know that the realy creates a ground at 222* so would that should mean that I need to make a switch that will ground that wire before the relay to finish the ground right??
thanks for any help

Have you looked at the tech article yet? If not go to the tech articles link off of the main page and read it. If so please note and I will advise accordingly.

ok I see this
"Option #1b
In addition, if you want the option of turning on the primary fan at the flick of a switch, it's as simple as adding another parallel circuit (spliced into the same location -- the green/white wire at the coolant fan relay). Essentially, this circuit is used as a "manual override" and I call this switch "Fan 1"."
but I'm not too clear on the actual Wiring of my switch
I do grab the Green/White Before the relay and then "by pass" the relay and splice into ground ??
not to shure but thats what I get
thanks for any help you might have

Find a grounding point under the dash, wire it to one post on the switch, run a wire from the other post to whichever fan relay you want to control. Splice the wire into the green/white wire. The factory setup will work the same as before and you will have manual control when you want.
