I was having problems with my 1984 240 DL wagon not starting sometimes. The indication was that the ignition switch contacts needed to be replaced. When I did this, I put some of the wires with spade lugs back on the instrument cluster in the wrong place. As such, the sond light is on all the time. My cluster has clock, speedometer, temp and gas guage. If you could please help I would greatly appreciate it. I have also replaced the fuel pump relay and will replace the wiring harness that connects the oil pressure sending unit, starter, hot start solenoid, fuel solenoid and distributor. Ironically, I had to go buy this off of a wrecked car I gave to the local wrecking yard. Thanking you in advance for your cooperation and assistance.
