Definitely helpful, Dan. We are on the same page.. mostly. You and I were both referring to those two yellow wires attached to the starter. In my case, one was solid Yellow the other was Yellow/Blue... or Yellow/Black, it was hard to tell given the condition of the wire
When I was taking out the CIS and fuel lines, etc., the harness had cracked in a few places and the wires were compromised. So, I do plan on replacing the entire harness with new wires, as I'm also upgrading the alternator, which necessitated replacing the old power/ground wires with higher gauge anyway. Since I'll be doing all that, I figured I'd create a whole new harness. That said, I'm still debating whether to just purchase a new stock connector for the harness or replace with a modern connector that would be much more waterproof than the open, plastic one that is on there now.
I was hoping to keep the new fuse box tucked away with the existing relays/fuses, but that might just be too hard to do. Still noodling that one. Where did you route the B+/B- wires from the MSD? They say they need to route to the battery directly. I've assumed there's an existing B+ in the engine bay that I can tap in to and I can just ground to the chassis, but haven't gotten that far to confirm yet. Will post pics once I leave my planning phase and get into the doing phase
Love this DIY community!!
