"The dash lights finally turned on grounding the red in my car its orange wire but how can I fix it so it can work in the right place. I checked the black wire that goes to the inside of the car..."
The problem is at the Alternator (not inside the car). You proved that when grounding the red wire turned the lights on.
The +12V is applied to those 4 bulbs at Key ON. The path to ground (for the bulbs to light) is from the Instrument unit to the firewall plug,
- then via the red wire to the alternator,
- then thru the alternator "internals" (I don't know how yours is configured) to the alternator body/housing,
- then thru a separate ground wire (usually Blue, and hard to see underneath the alt), from a the back of the alt (8mm nut),
- to a bolt that holds the alt mounting bracket to the engine block.
I can't speculate on the no-spark without knowing which Ignition system you have ('82 was a transitional year, and your PR location also adds to the mix). Is there a "black box" with a Blue label on top, down low on the right side, just ahead of the windshield washer tank?
Or is it a smaller Bosch unit near the coil?
