I have a 1997 A6 with the bose system and i am replacing the head unit with an aftermarket one so i can hook up my subs and etc... my only problem is that the back of the OEM head unit has two different blocks to harness into and the only adapters i can find only do tho bottom half... the top half if divided by 3 different colored blocks and have small pins and the bottom is just a black box with normal larger pins... i need both to hook up to aftermarket unit. am i just stuck having to do it all by hand or am i just missing something...
heres a link to the only type of adapter i can find that will only do half of what i need... http://www.sonicelectronix.com/item_...a-70-1784.html

Have you tried crutchfield. input your car info and search for the harness
