Just picked up a 3rd brake light - I have a 1995 993
Will the wires already be there tucked under the rubber that runs around back window? Or will I have to run a set of wires myself? Been trying to find any diagrams I possible could but no luck

Thanks

The two leads are inder the rubbler seal. Lift the seal at the center and you will see them.

Thanks - going to look tomorrow

The followng Technical Bulletin dated March 7, 1967 may be helpful. I can email the bulletin to you if you can't find it.

Gotta like the way Porsche is always thinking way ahead! In this case 46 years

Sometimes the wires are bad due to corrosion and vibration where they go through the glass.
If this is the case Search for this old post on how to diagnose and fix;
