Thanks for all of the advice! The yellow wire was disconnected from the switch solenoid. I plugged it in and the car started right up! Awesome! Who would’ve thought it would be that easy!
Glad to hear Rhettel. Now get some fresh gas in there, change the oil after you’ve gotten the engine good and hot, flush the cooling system, run some injector cleaner, clean the air box of any foreign objects, throw in some fresh spark plugs, and enjoy.
