So what would be a solution to fix that? I guess I mean what's the path of that wire? On the underside of the relay connector it's orange then the pigtail for that relay runs into a large connector next to the battery then ventures onwards.

Checked my manual further this morning. There is a splice in the harness that could be bad.
From the relay bank, follow the harness past the split to the ICU connectors, past the split to the diagnostic connectors, at the T in the harness go right and the splice/crimp should be there a few inches from the T..

Can't say that for sure. You don't HAVE to open the whole harness. Just the area I described, but I'd be tempted to open it right up. It appears that there will be 7 yellow wires crimped together there in some fashion.

so that must be the split for the ignition wire! On some of my older stuff i have used a post and put round connectors off of everything that needs to run off the ignition wire that way its easier to know where everything is. I knew there had to be a point somewhere that everything branches off of that one wire
