Aux port on stock head unit

[98_2DR]

I have found a few write ups on this but either I'm crazy or its not giving all the details. I would like to find a really good write up on how to add a aux port to my stereo for my iPhone/iPod has anyone done a good write up? I can only find some that give some details or the instructions are not very detailed. Any ideas?

I found bits & pieces using google search terms:

Delco radio aux input
Delco radio mp3 input
Delco radio ipod input

One of the youtube submissions was done by an eBay vendor, 'mp3radio'. He had the right delco model for my truck listed, with his mp3/ipod input mod. So I bought it ('cause mine was acting up anyway), and installed it last week. Works fine, except that my clock reset issue is now diagnosed to a faulting slave CD. Someday I may crack into it and document the mod for my records...
