Misterious wires

After 18 months trying our best to (mini) restore this well neglected (by previous onwers) 1995 sl320 (FA63W Brazil) we were unable to discover what are these 2 wires near left headlight.
one is a single red/white wire. The other is a pair of brown(of course ground by mercedes pattern) and black and white. Could any one please tell us what are those?

guess not. My headlight wipers works notmally
abs light is on. Perhaps that black white wire is the abs sensor car wiring. Abs light is on right now. Will check that last week.

Try downloading and installing WIS. Might be able to find some diagrams there as to what they could be.

Hi @Britojr , believe me, I would never suggest someone to spend $3200 on a subscription to solve a problem there are numerous generous members on this forum who have offered it for free which you can download and install. Some searching on the web will find you some threads of members showing how to install and run it. I didn't pay a dime thanks to them.

Still looking around trying to discover what those connectors do. No luck so far but today I was able to find an 104 diagram that shows the ring connector next to connector #100. getting closer and closer
