I have a problem when I engage 4 wheel drive the green dash light does not appear . It is probably the switch that is on the side of the gearbox . Also the diff locks will not engage just flash red . My question is are they dependant on each other ?

I don't have any trouble with my 4WD light coming on, but occasionally it doesn't want to switch off, but just needs the lever pushed completely forward.
While on the Canning recently, the rear diff lock wouldn't engage after a minute or two, and a bit of gentle forward & reverse, so I switched it off and didn't use it. Have just gone down and checked both diff locks, the rear one just flashed & wouldn't engage at all, while the front one engaged immediately with a distinct sound. I wouldn't use them at all, unless both front & rear lights had stopped flashing, the potential for horrific, and expensive, damage is too great.
The rear diff lock set up is a bit of a dog's breakfast! Wires partially exposed, and a stone/
rock guard that is barely strong enough for light gravel. When my ute was only a couple of months old, I travelled up the Strzelecki and hit a large
rock mixed in with some Road base they were spreading on one section. Didn't notice anything until later in the year, when we were travelling on a wet gravel road. A number of lights were flashing, including the 2 diff lock lights. Dealer suggested a cost of $1200plus for repairs, but they managed to keep cost under a grand, no warranty either.

Heck Bob, that cost is pretty steep to repair a couple of wires which might have been damaged or dirty connections.

True
Ross, a little knowledge can be expensive! I knew nothing about the diff locks, and the dealer knew only a little more than me.
Wires were severed flush with casing, and they only needed to renew part of the housing. Rest was labour, as I understand it, at least one axle has to be pulled to aid removal of the locking mechanism.

.
Bob, hard to guard against all eventualities.
My rear air-locker tube enters at the top of the diff.
Well up out of harm's way.
But that did not stop an errant flying
rock taking it clean off.
Luckily, my you-beaut owner-operator mechanic spotted it before I needed it during a routine after-trek service.
Bit hard to rig a stone-guard so rationalised that it was a one-in-a-million chance.
We'll see, won't we? lol
