Default Dewitts Dual Fan Question

Where exactly does the green (Ignition) wire go??? Ignition switch, tie into something that gets power when key is turned, etc.??? Since there is another wire (orange) with a fuse that ties into the starter or battery I'm not sure I understand.

I'm sure this is a dumb question. I'm good with nuts and bolts but a complete idiot when it comes to elec.

dewitts has good tech on his site

looked at the diagrams, no green. usually you can go to your fuse panel and tie it into acc. fuse. The orange wire is constant hot and the green wire activates the switched side of the relay
hope this helps.

If the green wire activates the switched side of the relay can I wire it to the positive side of the ignition coil?

are you using the controller dewitts sells or something else? My C3 came to me with the switched hot for the lame fan set up that was on it with that wire hooked to the coil hot, the problem is that till the fan stops spinning you'll back feed your ignition and give yourself a 'run-on' condition , that, till I just told you about it would have been lots of fun to find. The po had it stuffed under another wire. I'd find something not ignition.

Power to the A/C compressor is ignition switched and is close to the fan.
