Basically you want to get 12 volts to the 'trigger terminal' on the
starter solenoid.
That terminal has medium thick black/red wire on it...a push-on female
connector.

pull that wire, get 12 volts to the spade terminal is was on.
Some starter solenoid have two spade terminals there..and sometimes one
of those will fire the solenoid and starter.

where you get the 12 volts isn't too important as long as it's adequate
amerpage.
that could be the starter main post ( 13mm hex nut usually )
the alternator main post,
or the hot 12 volt post inside the black junction box ..
or heck..
think outside the box ...you could  get 12 vdc from another battery
sitting on the floor under the van , just make sure it's grounded to the
van too.
