[Mk2] [NA] Replacement engine re-wire confusion

[ChefAngus]

Hello all...i have recently switched my engine for a likewise secondhand 3s ge!
My problem is with re-attaching the loom! My problems are as follows:

Do the both the starter motor and alt both have two big wires bolted on to the terminal?

There is a black wire which is attached to the gearbox via a bolt. Where should the other end of this attach?

There is a another wire which looks like the one I just mentioned but grey, which is coming from under the fuse/relay box. cant see where this should attach.

There is a snap on 2 pin grey plug which comes from loom under throttle intake/water pipe connections and I cant find a home for this.
Pls try help, I know it is hard without seeing it.

the first one sounds like the main earth lead that goes from the gearbox to the gearbox mount n/s on the top ,pictures of these would help mate

Wire on the gear box sounds like an earth strap. That attaches to the body, should already be a hole close to the length of wire.

Am getting there...
I still cant work out where the small grey 2 pin connector which comes from under the fuse box goes(looks a bit like an earth lead but dont think it is, maybe it attaches to the air intake box somewhere).
Also need to know if both the alt and starter have 2 big screw on wires attached to there single terminal?

Cant post pics, sorry am using a mobi to post this at mo!

Thanks for your help ppl

the 2 pin snap on is for your afm. at the side of the airbox which faces the engine

[ChefAngus]

It cant be for air box as it is plugged in:-(
Seems there is another one on other side... Maybe they are for some kind of upgrade or something?
By the way what does afm stand for? Pls excuse my ignorance!

afm = air flow meter.
