You can remove all the parts of course. If you were planning to return to the original state with working jackpot the list of parts needed would include.....
Jackpot unit with coin chute
Jackpot trip arm (may still be in place)
Jackpot reset arm (may still be in place)
Replaced correct thick jackpot glass
Possible replacement of upper fingers.
Other items that would have been changed, the reel strips, the award card and denominator badge.
All that lot would probably cost around £100 if you can get them all and would look like all the other Hi Tops out there.
Wiring, it would be possible to work out. I did do a basic diagram of mine and if from the same company, probably is similar wiring. These wires are for the solenoid, lower fingers microswitch and upper finger switch. Decide on which course you want to take and perhaps we can advise.
