Interior roof wireing harness questions

Hi all,
I'm retrofitting puma roof light wiring harness to my 90 having purchased the right bit a while ago and could do with some help with how the wiring is laid out/clicks to inside the vehicle and confirming where the connectors go to.....

At the end that connects into the main harness at the top of the A piller by the drivers door, there is a clear connector with two wires and a black one separate. There are two of these in the harness a short distance apart so I presume they are for the interior lights, front and middle of the vehicles headlining?

Between the two, there is a tiny black connector with very small wires, I'm presuming this is something do with an alarm sensors??

At the far end of the harness, theres a grommet with a clear connector the other side of it, I presume this goes outside but where to and what for?

Any help appreciated as always.

As you've said -

The first two are for the interiors lamps - 3-way 'natural' (live and switched earth) + black (earth).

The black 4-way is for the alarm sensor.

The last one - 'natural' 2-way sealed connector, is for central locking on the tail door.

Thanks Paul, that clears that up then.

The end section with the grommet doesn't seem long enough to go anywhere near the back door, where should the grommet sit? 1984 90 V8 puma want to be.
