I should mention this car has had a very rare electrical issue: the horn will honk on very rarely when going around a corner. I always just chalked this up to an issue with the clockspring under the steering wheel. I did not see it as particularly important on this old car, and left it alone. I'm not sure any engine-critical wiring runs through the clock spring, or if there is any way an occasional un-commanded horn honk could be related to the problem causing the engine to briefly cut out or die.
Are wiring diagrams for this car available? I thought they would be in the Factory Service Manual (FSM), but have not been able to find them.
