1992 Manual GQ 4.2E petrol gas - Sorting a couple stray vac hoses

Morning everyone, I trying to take the guesswork out of refitting a few vac hoses. They were blanked off when I bought the car but I would like to sort them out and maybe find out what the purpose of a few vac/electrical items are. How important are they and should everthing be put back as per factory???
Please have a look at my photos if you have a similar setup can you tell me as clear as you can where yours are going, someone may even know what they do, I would be very grateful of some help.
1/ rear of rocker cover......2 vac hoses+elec conn
2/ near coil, looks like a diafram type unit, 2 hose + 1 elec conn
3/ larger dia vac pipes on intake near throttle body

I've got a similar setup mate - if someone doesn't come back sooner, I'll have a look under the bonnet when I get home from work and see what marries up (as such).

Pic 1 looks like canister purge solenoid
Pic 2 still looking
Pic 3 the short pipe on the air intake duct is sometimes blocked off due to the LPG system, the other one on the inlet manifold might go to the charcoal cannister (maybe0

Thanks for the tips/info
I shall try correcting the hose positions
