Help Identify 3 wires Please

[240260280z]

Down to the wire (pun).

So far I have figured out where all wires go from the wiring diagrams, colour coding, fsm drawings and support from this forum (thanks).

I am down to 3 that I am not 100% positive about.

The dash harness to the fuse box has 2 blue wires with in-line fuses and one black wire. All are heavier gauge:

1) One of the fuse holders is toasted looking. It also exits lower in the harness and it also has a black protective sheath around it. Am I correct to assume that it goes to the blower motor harness or defrost?

2) The other blue wire comes out ~ 3" higher in the harness (near the taped back fuel pump connector) but I am not sure what it does?

3) Finally, where does the hefty black wire (with protective sheath) go?

I think the fused blue wires are for the blower and rear defrost. My guess for the black is the cig lighter.

Thanks...that will work. I am guessing the 30A fused sheathed blue is the blower and the 20A fused non-sheathed is the defrost.

Now to throw that dash in.

My early 70 has a long blue fused wire that goes to the blower. The long black wire looks to me if I am seeing it right like a load (rear defroster?) because it is an exposed male connector and might short a power source to ground if left unplugged. That seems logical to me but may not be correct.

Thanks again! Now that I am moving forward and throw the dash in.
