the voltage regulator on fire wall boxfirewall or some'ing like that
says 14 volt 100 amp
so its been converted to 12 volt
{and you cant trust battery cable colors at all
if back yard save money using used parts type has worked on it}
the nag.. cables should go to ground same ware motor or fame or both
pos. most of the time go to starter and a smaller wire feeds the rest of
the truck
with that pump motor back there a bigger cable would need to feed its starter
and it mite or mite not have a anltnater/generator on it
good luck
