Have a few questions. So I have a Ford Focus. And the Alpine CDA-9812RB. 1. This adapter cable from Alpine to Ford, is there another cable for all Ford models or is there only one? So I have the HU from a buddy and he had a Ford Escord, can I take the cable for the Focus? 2. I want to connect to the HU the 4 Standart LS. Does it bring what if I pull an extra power cable from the battery to the radio or is the cable sufficient for what is normal in it? a already asked my dealer but he only meant that you have to try it. My buddy from whom I had laid the HU an extra cable but didn’t notice any difference. 3. How can I put the cables from the front in the inside and in the trunk of the Focus? Is there somewhere an opening where you can easily reach it? Thanks already!
