Help identifing Mystery wires in Frunk

[Damon88]

Here I'am again needing help from the experts after my long google/Bentley manual and forum search..

First up is a wire coming through front fender into the trunk on the driver side.

Second is a small harness with a plug that goes into the Fues panel. Only had the car a week and still finding little gems that keep me up a night thinking... haha any help would be much appreciated.

I'm pretty sure the harness in that last picture is not stock.

Also, I suggest you add a signature to your profile with your car model/year.

I’m guessing it is old alarm system wiring.
No wires going through the fender like that on my 78.
Did someone add fender side marker lights?
They were added to later years in other markets.

Interesting.. Thanks for chiming in. Definitely no side marker lights installed. I will see if I can trace the wires back and see. Cheers Timmy.

These factory drawings may help identify circuits using wire colors.

And for options like power windows, A/C etc.
