electrical questions - what are these?

'87 JDM BJ74 RHD 24 volt 13B-T Japan > Canada > USA/Mexico > USA


Proximal to left headlight

what are these 4 seemingly unused connectors for?

From Left to right:
1) Female squarish plug with 5 wires (was taped up - guessing this was for original headlight which may have been changed?)

2) Black round two wire female

3) White T shaped female with 3 wires and 2 terminals (fog light?)

4) round blue female 2 wires (same as 2 above but blue not black)

Did you ever figure this out? I also have some white plugs farther up the wiring towards the firewall that are seemingly unused.
