Hello, I have a 2000 Taurus LX FFV that I purchased for my son and am having a difficult time trying to figure out what's wrong with the stereo. It will not power on at all and I've checked all the fuses and none of them are burnt. I did some searching on this forum and came up with a few ideas but have a question or two that I'm hoping someone out there can help me with. I found the RCU that is in the trunk and noticed that one of the three plugins on the RCU (the one furthest to the right) is empty. There are some unplugged wires there but the male end of the plugin does not match the female port on the RCU. The loose wire has "BATT" and "ACC" tags on it but I cannot figure out where that wire goes. It has a three prong male end and does not match the missing plugin on the RCU. I am just wondering if anyone out there has any ideas before I spend the $60 on a used RCU just to possibly find out that the RCU isn't the problem. Does anyone know what plugs in to the farthest right port on the RCU? That would be helpful. Thanks in advance.
