What Rusty says about the headlights if you are driving at night.
When I've driven cross country in an A body I come off the road after dark because of the increased danger of just about everything happening in the dark.
That being said I drive at night everyday cross town for work at night in an A body.
So do that upgrade anyway.
You mentioned "extra orange box". I don't know about that.
But I gave up trying to find a reliable ECU and have installed these on more than one car with great results.
Even if you carry an extra ECU and resistor the coil needs a spare if it's old.
Check your ignition voltage at points in the circuit and be sure you have 12 volts at all points. (When starting)
I suspect it may be low with old connections.
Maybe not.
And lastly, related to that, carry some good prints in case you need them.
