Looking for Speaker Wire Harness Part Number

I am trying to get the install accessories for speakers for my truck. Does anyone have the part number for this?

I am trying to get them cheaper from sonic electronix but I can't find the exact part. i've done some googling and searched these forums but really haven't found anything.

EDIT -- The part number for ANY compatible speaker harness will do, i don't care if it's the one crutch carries or not.

 

Got it!!

If anyone is interested, for posterity's sake, here is the part --
Metra 72-8104
