have a couple questions, that hopefully somebody can helpout wth;

1. Have a 71T targa that I'm installing a new OEM Porsche seal along with the rear Targa glass, Original had the 3 small holes in it, along with, 2-3 "slits" going to the holes themselves. I don't know if the "slits" were factory or not.? I know that I have to "drill/punch" the 3 holes, but don't know on the slits.? Any help there appreciated.

2. Wondering if anybody has a simple wiring schematic on where the defroster wires connect to.? There are the black "jumper" wires, red/white power, red/blk power and the brown wires (grnd.?) I see somebody put something together for a Coupe, but was told it's different for a Targa.? Any help there appreciated as well. Thx
