Default mx5 wiring bits question

OK so Im plugging away at the wiring and following some good diagrams bit I have found a few things that I am not sure of what they are ......

I know its not in a haynes but I did start one! the chassis is on my shed wall!!
first the rats nest, I have tracked and labeled everything in blue and then marked the keepers in red (things that I can reattach to the motor)

but what are these
1, the heavy blue wire coming from the fuse box? its a single spade connection


2,the small yellow connector that is with the coil connections


3,this thing, its a bit of an orphan

The blue wiring is for the heater fan unit. I will have a look at the other later to see if I can match them. There were a lot of spare ones on mine that I cut out. One of the photos has a little block attached. Ive been wondering what this does as ive got the block in my garage and not on the car (si it cannot be that important)

Attaches to the Heater unit I believe, mine attaches to nothing.

2,the small yellow connector that is with the coil connections.
Pretty sure there is an ECU temp sensor just near the coils that this plugs in to.

3,this thing, its a bit of an orphan
Not sure but a readable picture will help identify it?

4, the brown one here, its on the connection that heads to the radiator
I think this one is also a temp sensor for the cooling system.

What colours are the cables going to each of the plugs because that will help a lot to identify them?

Cheers
Stot
