Which wiring harness do i need?

Hello all and new to the forum so take it easy on me please.

This has been beat to death around here I imagine but I can't find the answer I need. I am thinking of installing a cruise control on my new 2013 4wd regular cab with 5 speed manual transmission and of course the 2.7L 4 banger.

this address http://www.villagetoyotaparts.com/showAssembly.aspx?ukey_product=2371647&ukey_assembly=348292 shows the cruise control switch, a clutch switch and 2 different wiring harnesses. both harnesses have the part number of 84633. One of the harnesses is 11.86 and the other is 29.08. On another toyota parts web site is says one of these harnesses is with bluetooth and one without bluetooth. I am only assuming it is talking about the radio and if it has bluetooth for your phone. I don't know. I need help on this one to order the right part.

Also, the clutch switch, is there a separate harness for that? I am not seeing it connecting into the system anywhere.

Thanks in advance!
