Ok, i currently have an extremely old sony HU. I just bought a Blaupunkt Santa Fe. I tried instaling it in my self but the sony has about half of the cords connected to the HU compared to the Blaupunkt. The sony only has one set of wires going into it, i presume they are the front and rear speakers as well as the antena. I went to some website to find the colors of the wires in the car, which is a ford contour 97. i looked at this list and then took out the sony and i dont think that i found one of the colors that matched. can some one help me out?
