i just put an after market head unit on my 91 civic the thing is that it does not save anything like radio station my bass and every time i turn the car off it resets it self how can i connect it so it dosent do that ive checked all the wires and i connected them correctly i have seen this happen on my friends hondas can some one help me and solve this

 

you prolly connected the yellow(constant) and the red(accessory) together using the white/green. If you did you need to wire the yellow to white blue.
