I attached a slideshow to this message. The first picture is the battery cable I pulled from the car. I included 7 other pictures of electrical issues I'm facing. I made the mistake of allowing a friend of my son to work on the car. When he lost interest he left the mess shown in this slideshow. The car has an aftermarket equus gauge cluster (tach and volts) which don't work. The 2nd-4th pictures are of the gauge cluster. I don't know what kind of ignition system it has. The 5th and 6th pics are of a small junction box screwed to the engine compartment-side of the firewall and the coil. There's a black and green wire that go from the junction box to the coil. The car also has power door locks that don't work. The 7th and 8th pics are of a cluster of wires that have been pulled down from underneath the drivers side dash. The black box at the bottom of the picture has an antenna wire attached to it, so I think this mess of wires are part of the power lock system. I just need to know where to begin to put this back together. But, the bottom line is that the car runs. None of this affects the basic operation of the vehicle. Thanks again for your help!
