Nothing better than getting rid of those electrical demons. That's why I replaced all of mine too. No sense in risking a fire when you've put that much time and money into it. Keep at at it. The light is just around the corner!
Here's a perfect example of how things go for me. So I'm doing the alternator wire back to the battery and realize I need a fusible link. My output wire is 8 ga. so I need a 12 ga. fusible link. No 'regular' fuse here, the link is a slow burn and will absorb spikes better than a fuse. I have three 14 ga. but no 12. So off to the parts store.
I seriously went to every parts store in my town and a trailer place, not one of them had one stupid 12 ga. fusible link. The guys at the old school parts store in my town like to laugh at me when I come in because I always seem to find the oldest obsoletest wiring component they have on the spinning rack.
So now I have to order online. If I order now, the parts will show up on Thursday night. My weekends are filled with kid/family stuff so now it's literally a week before I get back to doing what I started.
I guess there are other things to do while waiting on the stupid wire but it can be pretty demoralizing sometimes.
