1988 - Carrera 3.2, Left Turn signal assesmbly - New Vs old wire color coding
 

Old part- Color coding on turn signal assembly was Black/White, Gray/Red , Brown

New part is Blue, Yellow/Green, Brown.

Any guidance, thx

Parking Lamp Housing Wiring
Old New
Brown Brown Ground / Common / marker lamp - tab furthest from cable.
Grey/Red Yellow/Red + to parking light & side marker
Black/White Blue + from flasher to signal light

The Q&D way to do it is: (lamp housing to connectors in headlight bucket)
Brown from housing to double connector - brown leads (there are two wires)
Blue from housing to other spot on double connector (turn signal)
Yellow/Red from housing to single connector (parking & marker lamps)
Hope that makes sense.
