OK I bought the Hayden REaly/Switch Kit (Like the Tech Article) and I have a few questions.

There are two wires going to the fan. One i black and the other is black with a red stripe. Is the stripe negative or positive? I don't want to sound like I don't know anythin, but I do... I always get mad becuase sometimes the stripe is positive and that confuses the hell out of me. I know it should be negative, but I just want to be sure.

I have to wire another wire to the A/C Clutch. What the hell is that? Where is it? And do I add the LED here to tell whether the fan is on or not?

Now i want to use a switch. I would assume that for the yellow wire (supposed to be attached to a switch) that one end is the yellow wire to the relay and for the other end, its a 12 Volt positive, IE from the Acc position of the ignition? That would make sense.

 

I'm assuming you're talking about the fan wires themselves and not what came with the switch. In that case, the black/red stripe wire is + & the solid black is -

A/C clutch (the big ugly pulley looking thing), is on the A/C compressor. There is a small flat plug running just under the back of it (should be fairly easy to see). If I'm not mistaken you need to hook the fan switch to the green wire (check your instructions on that one).
If I were to attach a indicator LED to let me know when a fan is running, I'd run it off the power wire to the fan itself since it is switched on by the relay (wiring it to the A/C would just show you're A/C clutch is on).

I'm lost on the last part of the question about the switch.. I've got an adj fan switch on my camaro (dunno the brand) and all it required was a ground (for the relay), power from the battery-battery power to the fan, +12 switched ignition (for the relay) & a hookup to the A/C clutch.. nothing about any switch. Of course, it also only came with 1 handy roll of all black wire...
