Headlight issues

[Rascal21]

It has previously been tampered with:
Aftermarket 30A relays on 12v terminal, using red-black & red-green wires (Which in this case is for high-beam/flash I think?) for switch rather than power.
And they are earthed directly to chassis as well.
There are two wires under the engine bay fusebox which has been tampered with, a black-orange wire has been cut off and taped, and another one which color I cant remember and it has has been spliced and earthed.
Other than this all seems Original, including the different wires that goes to the Right side headlight.

Mine is a 1984 EDM Zenki Levin Coupè, and I am pretty sure it`s not a ex-German car (Short-pin in place of the Dimmer relay, normal 3-pin headlight relay where it should be)

Thx a lot for answering! You`re way more experienced at this than I am.
This is one problem I just cant wrap my head around.
