Stereo wiring

[Cheeto]

I just installed a stereo on my own and I have everything working except the memory. I don't have enough money to get it professionally done so I was wondering if anybody could help me with this.

if i remember right its the red wire with the green stripe. teat the wires by using a test light with the key off ,probe the wires one should be hot this will be the memory wire . now turn the key on and reprobe the wires now you should find another wire that is hot this is the acessory wire. now on the radio side the red wire goes to the acessory wire and the yellow wire goes to the constant hot wire ( one that is hot with key off)
