Hello! I need help. I have an M47 and the speedo, odometer and shift light don’t work. Just put in a different speedo with new gears. Still nothing. Reconnected frayed wires at sensor. Nothing. I pinched the three wires for the Speedo and reconnected and nothing. Why would the shift light be out too? Help!

My car is an 90 that had a 1986 speedo in it and now I have a used proper 1990 one. Before it went out it, the 86 one would not work and you could slap the dash and it would come on. I pinched the wires and that was not it. Do you know where the wires go from 2 wires at the sender to one wire at the back of the speedo. Is there a junction box type thing?
