This is my situation. I have tail ends thats I can't remember where some of them belong. I did make an effort before I stripped the loom out before I painted inside boot by marking all the different wires etc.

And yes I know its a mess but I just wanted to put it all back together before I total forget what's what.

Unfortunately your photos tell nothing. Have you looked at the diagrams and this to trace the colour on them?

It looks like someone has been in there and made some changes so it’s very difficult to ascertain what is what.

Got to help yourself a little, thicker white is a headlamp, I forget if it’s low or high beam.

Black/red is brake light circuit, both clearly identified on the diagrams.

Great. If all else fails a multimeter with a buzzer and a length of cable on one probe will be invaluable.

Usually once you get back to the factory wire it’s simple.

Far easier than a D-jet ECU harness which is all just white!

Again if you can’t figure it out do give us a wave

The black/white wire is main 12v feed to headlight switcher relay. (Connects from light switch).
The white wire is one high beam (blue/white wire goes to speedo warning light).
As stated, the black/red will be brake light circuit which should have a 12v feed from the fuse block.
I would advise removing all those scotch locks, none should be necessary for stock wiring.
Any repair would be a better option IMO.
