Simple quick question on fuses and gauges?

I hope that is the case anyways. I am at work right now so I cant actually look at this thing.

Heres what i got:
82 cj7
87 cherokee 4.0 motor swapped(and running, just finishing up some small stuff now)
This whole time I was worried about how i was going to get the voltmeter to read, as I was thinking for some reason that the white wire coming off the alternator going to the fuse block was where the gauge got it's reading.


my voltmeter works perfectly, maybe even better than it did before.

the problem i am having now is that my oil pressure, temp gauge and gas gauge are all not functioning.
I have a 4.0 in it. . . but. . . it is using all the cj7 wiring/ sending units. . . so in a perfect world... swap the sending units over... everything works. . .


The part that is throwing me off is that i didnt touch anything to do with fuel tank sending unit, so it should at least be working... well they all should, and all worked fine before i started the swap. . .

so my question for you is a simple one. . .
is there a fuse that allows power to the gauges that i might have blown?
even though the voltmeter works fine?
what exactly is the white wire coming off the alternator for ??
thanks in advance guys
