The driver's side alternator charges the battery closest to the headlights,
where the pass side one charges the one closest to the firewall. Mounted on
the firewall right behind that second battery are two junction blocks. The
topmost one is the 24V junction block, and the positive lead off the battery
nearest to it physically should go to it. The positive lead from the slave
receptacle also goes to this bus.

24V positive to the bus bar I just talked about. Make sure the system
ground is good at both the vehicle body and the engine. Can't see how there
would be 'extra' wires unless someone's messed with the bus bar and
disconnected the radio leads and/or the slave leads.

Could be a few problems. If the batteries are present and are absolute crap,
they'll act like a resistance and drag the available starter voltage down
via the slave. The engine ground could also be poor, which would make the
starter spin slowly/erratically. Might want to check the starter bolts too
as a matter of course. Most of them were loose on the trucks I've had
anything to do with.

Be really careful of used pumps, or even c. 1984-85 NOS pumps advertised on
the open market. The problem is that the 1984-1985 (and possibly beyond)
pumps had a composite part inside which I remember as "counterweight
retainer clip" which unfortunately would physically start to dissolve thanks
to additives introduced to diesel nationwide AFTER the pumps were produced.
This stupid retainer-thing then starts shedding bits of itself which then go
on to clog up your Cold Advance Valve, making for hard starting and a host
of other ills thanks to the ongoing particulate contamination. I imagine
any NOS pump dating from the same era would also have the same 'time bomb'
waiting to go off, which is why I've stayed clear of buying one from the
surplus dealers myself (though the deal at Coleman's Surplus was certainly
tempting a couple of years ago - something like 220.00 as opposed to 800.00
CDN.) The rebuilder I'm just about to take my own 1009 to tells me that
there are a ton of other upgrades they do in the course of rebuilding the
pump too, so I've pretty much decided the expense is worth it in my case, as
I'm driving mine as general transporation and for work. I have come across
two pumps with that exact problem - including my own truck - and both have
been 1009s.
Also, in replacing the pump yourself you run into a timing-problem. There
are lineup marks on the pump and casting of course, but from what I
understand from the diesel guys, using those alone is a bit like setting the
timing up on your gas motor to TDC and walking away. At the shop they have
a fancy dynamic timing device which evidently senses the diesel pulses as
the individual injectors open up, and that's what they use to set the timing
to factory specs. Again, I'm no expert here - but that's what I was told.
They couldn't even time one of our USMC HMMWV's we got straight from the
Gov't because the pump was installed so far off that the timing adjustment
needed was way out of physical range.
