2000 ce instrument panel swap w/o tach to w tach, does this afect???

#1
Bought an instrument panel for my CE year 2000, today I noticed the left signal light was off and the right side was on.
A couple of minutes later the left side went off, and instrument panel lights off.
When the instrument panel was bought and installed the signal light at the panel did not work.
However I pressed the rear def switch and goes on steady. Plz let me know what's the problem
Thnx
