Idle problem.Thought fuel, but it was bad ECU

My emergency kit.
Goes with me every where in a Chrysler.
It all fits in the case.
(Those are wiring diagrams)
I figure if the key switch goes, I can piggy back it at the steering column and get going.
I actually had a dist cap go bad on a four banger Honda Civic long time ago.
I've converted to manual steering and brakes to simpliy things on the belts, etc.
Starter, battery and alternator are time change items.
I'm counting on the engine and trans to get me there.
