1998 Plymouth Voyager lost all power to coil and starter

It is the heater core that went same day as speedometer and odometer

I 3.0 engine. Hve checked the ASD relay power to terminals 30 and 85

at ignition switch the pink wire with black stripe has no pwer and no pwer coming coming from key lock any position

Orange wire to crank and cam sensor is run position gets only 1.5 volts. When cranking over engine orange wire gets 2.7 volts. Manual says 8 volt supply. The big pink wire going to the ignition switch which is possibly a 12 guage wire has only 5 volts. Did taje ignition switch apart. Had a little arc present. Cleaned and sanded terminals. Orange wire going to junction box inside vechicle was repaired. Appears had melted and was repaired before. Checked BCM NO corrision, bent pins etc. The diagrams that u sent are hard to read very small on computer. Tried to enlarge but goes to blurry. Any way possible to enlarge the area that was circled so that can read and not as blurry. Still no change cannot locate what the problem is checked everything but seems power being drawn away for starting circuit. But thank you for the diagrams
