Hopefully there are markings on the old t-stat as to what terminal is what.
on the honeywell 8000 use the heat pump labeling and then the standard wiring would be
R- red
AUX-white
Y- yellow
B- O/B
C- black
G- green
There should not be a bare wire, it probably just has the insulation stripped back way too far.
You should probably open the furnace and compare the terminal label in the furnace to the wire color. normally yellow and blue pass through the furnace and are wire nutted to wires going to the outdoor unit. In the furnace the white wire will connect to the w or w1 terminal. also, you will need to set the Honeywell stat to have the following parameters.
170-7
190-1
200-0
other parameters that I did not specify, you may read the manual and make your own decision but I recommend factory settings for the other parameters

Sorry Iasumed you had a heat pump t-stat. You will need to exchange to a heat pump t-stat

is this a heat pump or straight cool with heat strips?

Wire nut or tape the black off. The red is normally 24volt supply power to the t-stat. Blue may or may not be the common. Have a voltmeter?
SOURCE: I have a Red, White, Blue and Green wire , need to
From what you describe you have a heat only system with no AC. If that is so, then you would wire it as follows.
Red wire = RC (leave the jumper in place)
Green wire = G
White wire = W/B
Blue wire = is unused because the thermostat is battery powered and does not require a common wire.
I reccomend you consider not using the Hunter T-stat. They are so extremely problem prone and unreliable. You will be much better off with a Honeywell or White Rodgers T-stat.
You will also need to program the Hunter T-stat for your system per the instructions.
