Hello- today, I was wondering if there is a GPS in the DC-8-71. If there is how do you use it?

There's no common "FS TYPE" GPS built into any of the HJG DC8 panels .... intentionally !!!!
A KLN 90B type system/GPS is represented in each though (with the exception of SHIP ONE 1959) .... and which works on similar but slightly more complex principles.
My understanding is that a flight route must first be generated "within FS" (with all of the necessary track and NAV data between ones departure point and destination) .... and the KLN 90B system then being used as "basically" as follows ....
D BUTTON = toggles GPS display ON/OFF.
ENT BUTTON = toggles AP NAV source between NAV1 and GPS .... replacing the GPS NAV switch typically activated in FS when using the GPS to drive the AP. When GPS becomes the AP's NAV source the titles "GPS" are indicated within the lower right corner of the display.
CDI/XTK/FLY KNOB = select XTK display modes ....
RIGHT CRSR BUTTON = toggles CDI mode sensitivity between 5.0 NM per mark and 1.0 NM per mark.
In CDI mode the following data is indicated o the left side of the display ....
LINE 1 = set scale (5 NM or 1NM are available) .... with the pointer indicating the extent of any cross-track error.
LINE 2 = bearing to programmed NAV waypoint.
LINE 3 = ground speed.
LINE 4 = NAV waypoint ID.
In XTK/FLY mode the following data is indicated on the right side of the display ....
LINE 2 = distance to NAV waypoint.
LINE 3 = estimated time to waypoint at the current ground speed.
LINE 4 = AP source .... either "GPS" or "NAV".
I've never used the KLN 90B.
Old fashioned VOR to VOR NAV (and desd-reckoning) .... aided by official paper NAV charts .... are more than sufficient for the purposes of the transcontinental/transoceanic type flying which I do .... and replicating the era of flying "I prefer" to replicate for the benefit of "my own personal enjoyment".
Best way to learn the KLN 90B is to fiddle with it .... just "suck'n'see" !
One can't break anything doing that !
