Camshaft Position Sensor

[98'Explorer XLT]

I recently bought a '98 Explorer XLT 4.0 SOHC with the check engine light on.
I noticed that it was a little rough at idle and that the RPM's spiked just a bit upon starting usually around 2000 RPM's for about 4 seconds, then it comes back down to normal. I took it and had the codes read. It came back with 3 seperate problem codes:

P0340- Camshaft Position Sensor
P0300- Random/Multiple Cylinder Misfire
P0174- System too Lean

I've researched the codes a bit & found that all three may be related to each other. My proposed fix to the problem is replacing the Camshaft Position Sensor as well as performing a good tune up: new plugs and plug wires, fuel filter and air filter.

I have a couple of questions.

1.) Do you think that this is what's causing the check engine light and the rough idle?
2.) Where exactly is the Camshaft Position Sensor? I know it is on the camshaft, but have no idea as to where to look for it. A picture would be greatly appreciated.
3.) Do you think that this will fix the problem?

Thanks in advance for any help or tips you all might be able to provide.

I came across mine when I was replacing my ignition coil. It's right beneath, dead center. If you remove your coils, you should see it below. Mine had 2 little bolts. I had already bought the replacement, not knowing where it would go, but when I came across it, I knew what it was because I had something to compare it to.

Do you guys think that replacing the sensor will fix the rough idle and misfire??

I just finished replacing my timing chain tensioners and guides and after putting everything back together I am left with a wire that I can't find a home for. It originates behind the thermostat housing and is about 15 inches long. It is a two prong plug with a wire retaing clip just like the one that goes to the camshaft positioning sensor. It's the only other wire that I came across that had the metal retaining clip. Does anyone know where this goes??? Thanks

Ditto, I thought you had the crank wires, and were looking for the camshaft sensor. Good,
