I want to install it to a pioneer bluetooth unit and I wanted to know if I can do that. It does have the option for an AUX slot in the headunit but I didn't know if there was gonna be any special wiring.......

What do you need the aux for? An mp3 player?

Most recent headunits have multiple audio inputs so you can just attach a cable but my preference would be to use a USB port if that option is available.

You want to connect you PC's (laptop's?) "LINE OUT" to an aftermarket head unit. You just need the proper cable.

Use this diagram that was posted by emass a looOOoooOng time ago.

You'll notice that the aux plug behind the stereo has 5 wires...2 of which you can just twist together, tape and leave hangin. The other 3 require you to combine the 2 negatives of the RCA's and splice to the common ground, then splice the left and right channels to the appropriate positive leads on the RCAs...connect these new RCAs to the AUX input of your new HU and the stock AUX in jack will work....hopefully.... :p
