Where do these connect?

I've started to install the wiring loom and have some connectors that I'm unsure of. Any ideas?

I think that the green along with the black with green tracer are the horn wires. The green being ignition controlled live, and the black with gren tracer being the earth from the horn push. None of my cars are this new but the withe connector looks like the brake warning connector if your car is a dual circuit brake car. They usually attach to a shuttle valve arrangement which has the electrical connector and 4 brake pipes running to it.

 

@david-barber I think you're right with the white connector. I took another look at the brake master cylinder and there is nowhere to connect it to, but then I remembered that I removed a broken switch a while back, so I'm almost certain it plugs into that.

I'm not sure those green & green/black wires are for horn though. This car came with 2 horns, one on each side and I think I've identified the connectors for that. They look like they've got a tubular rubber hood over them, unless these are for something else? Pics below.

I was referring to this wiring diagram for the horn wire colours. http://www.advanceautowire.com/mgb.pdf

I think I've found it. It's the wiring for the radiator thermostat that controls the electric fan.

Brilliant, well done! Sorry to send you in the wrong direction.

 

left to right -

1 & 2 radiator fan switch

3- brake fluid warning light

4 & 5 - Hi and low horns

If it ain't broken don't try to fix it as if you do it will definitely break
