I think the other fellas did as good of a job as any of us could without knowing the exact MSD box and other particulars of your setup.

Extra wires can be cut back and disregarded, but if you do that, then make sure to pull the fuses that power those wires so that the little bit of copper at the ends doesn't ground on something and cause problems or worse (fire)

Personally, I just roll back all the wire into loops, and then zip-tie it up and away from everything or tuck it under the carpet if I can (still remove the fuses though). You never know when you may want to add something in the future: heated seats, power window & locks, electric fan, fuel injection, USB power, etc. It's just nice to have an available pre-wired circuit for those unforseen 'upgrades' to make your old truck fit in with today's modern creature comforts.
