Josep,
The feed for the console comes from under the dash in the center very near the top. There are two wires, a green with a yellow tracer and a black with a blue tracer. Both are female push in connectors. The console has an intermediate harness of these two wires that is routed under the carpet and emerges at the hole in the carpet near the shifter. At the shifter, the two are joined by a short black lead that has a ring lug terminal that attaches to the body a few inches in front of the shifter. It shares the same grounding screw as the indicator light used in automatic transmission. The three console leads are connected to that harness there. All three wires from the console should have male push in connectors, the three from the shifter should be female push in connectors. At that point, it's black to black, green-yellow to green-yellow and black-blue to black-blue. The black-blue circuit is activated by the door switch or the courtesy switch function of the headlamp switch and that provides power to the console rear lights, the green-yellow is hot all the time and is used only for the console door lamp when the console door is opened.

You need to get a set of assembly manuals.
