All my electrical woes.

I am attaching some pictures I took this morning of the fuse box, the left side of the instrument panel and the right side of the instrument panel. You can see on the fuse box the red wire added to go to the tach. I do not see a box going to the instrument cluster, just a cylinder. Would that be my voltage limiter? So far nothing real obvious that looks burnt or pinched. I checked a lot of the push connections and they all seemed tight.
