6.0 positive battery cable question

BLUF: Can anyone provide a good photo of the positive battery cable on the passenger side of a 2003.5+ with the 6.0?

I'm trying to correct what I can best call a "hack job" on my truck's battery cables. Apparently a previous owner didn't want to spend the money to replace the A to B positive battery cable (~$125 from Ford so I can sort of get this), so they cut the ends of several wires, crimped on new cable ends and, using a $5 Wal-Mart special positive battery cable, spliced everything together on the passenger side battery. It worked, but I suspect it caused issues with the cable over time. There is a section in the middle of the cable where it passes in front of the radiator that has become stiff and not pliable.
Anyway, the cable is shot and is being replaced with a factory part. My concern is that I don't have the necessary connections on the existing wire harness to install this new cable. Does anyone who owns a 2003.5 (or something close to that) with the 6.0 have a picture showing the wiring? Specifically I need a photo showing the section on the passenger side that connects to that battery's positive post, as well as a separate harness that appears to contain four different wires coming together as one that should plug into the positive battery cable. Hopefully this isn't too vague, particularly since as a new member I cannot post pictures yet (10 post minimum if I recall correctly), and really don't want to just throw a bunch of BS posts up to boost my post count. If I get to that point in the interim, I'll see if I can upload a photo of those wires. Additional info available as able. Thanks in advance!

Is this what you're looking for?





I did a wiring upgrade but these may still help you

Wow... You guys know how to deliver. From what I'm seeing, looks like the first pic from Master_Chase has what I'm looking for. There are four grey wires that come together, but it looks like the PO replaced the end on that cable. Do you happen to know if that particular connector attached directly to the battery, or if it plugged into a pigtail that hangs off of the battery cable? (this would be easier if I could post pictures; sorry about that...)

Wow!!! Just what I need! This looks like the positive terminal on the driverís side battery.

Where does the smaller cable go? I have a 2006 F250 with the 6.0 diesel and the batteries are constantly draining. This small cable is shorted to ground. When the batteries are fully charged, the drain is ~ 4A. Disconnecting this wire seems to kill everything.

Iíve traced the wire as best I can. It seems to go into a group that leads into the bottom of the fuse box thatís in the engine bay, just in front of the firewall on the driverís side. I canít check to see if the wire itself is shorted somewhere unless I can find the other end of it.

Whatís the problem??????

I think your talking about the one that runs to the interior fuse box under the steering wheel. IIRC it's only 4 bolts to remove it from the dash.
