[MR2] Re-wiring problems:-(

[Angus Harvey]

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.
