What kind of wiring harness do I need?

Ok, sorry for the question but I figured I'd rather be safe than sorry. I just ordered a pioneer avic x940bt off of Amazon along with steering wheel controls and the double din face plate, but I still need to get a wiring harness to make it easy on myself, but the ones I'm finding say it's for the 4 speaker (I'm assuming the non-JBL sound system ones) I haven't opened up the stock radio to see if it's just rca's that would plug in directly or if I need a different harness since I have that JBL system in my truck (05, so second gen if that helps too). In short, will this right here be all I need:

Thanks for the help guys, I'm hoping to get it installed along with the bypass Friday or over next weekend. Also, I've read the bypass is the same is the 930bt and I've found videos of that, but some have said it didn't work or didn't work over 15mph for some reason, did they just do it wrong or is the bypass a little different?

I just found this as a review:
"Do not buy this harness if you have a Toyota Tacoma with a JBL stereo. There is a built-in amp. in the current system that requires a much larger harness to hook up an aftermarket stereo. The harness you will need will cost about $75-$100. Hope my error is helpful for someone else." is this correct or did this guy just mess up because there were around 10 other reviewers that installed it and said it worked perfectly, I can't believe that only 1 out of the tacoma reviewers had the JBL sound and the other 10 or so didn't. But I did want to be sure

ok, so this is what I need: http://www.ebay.com/itm/2003-2011-S...fits=Model:Tacoma&hash=item4cfcaec874&vxp=mtr ? haha, I'm clueless, I didn't realize the jbl sound was as uncommon as it seems to be.

 

Return it and get it from Crutchfield they will give youall the harnesses and fit kits you will need.

 

Hey Robbie,

Take a look at the 127tato on our site. That's the PAC TATO. It's the integration adapter you need for your Tacoma.

Hope this helps!!
