Headunit Install Questions for 92 5.0

I recently purchased a 1992 5.0 from a friend and he used to have a nice system in it..........but when he sold it to me he jerked it out and now im left with trying to figure what wire goes to what...........there are 2 sets of wires that have the original connectors on them for the stock headunit......and then there is a set of wires that are all different colors ranging from pink to orange w/ blue stripes..............well i bought the adapter think that i could use it but when i hooked the adapter up to the stock adapters i doesnt work.................and from the looks of it he had the system hooked up with all of the funny colored wires..............where do i start and where do i get an adapter for all the diff. color wires??????????Can some one please help ???????????

i iwll post pics of what it looks like in a few mins..........

yeah and what is very funny is that i have that same diagram on my computer and i couldnt really understand it because when i printed it it came out small..............lol

ok the first pic is of the wires i think he ran his system off of.............and the second pic is of the stock head unit wires................has any one else had this problem?????????
