Bypassing Ballast Resistor / Installing Pertronix Ignition
That's right! With the original wiring, the one "dark blue"-wire goes to the coil 12V+ (no changes needed). my pertronix doesn't hit the cap (I could keep the original cap). I like the idea of "the mystery black box" haha...
I checked the service manual's wiring diagrams and was surprised finding the original wiring in my car with the exact color codes...
Guess I'm going to "jump wire" the existing ballast resistor with an "invisible" cable on the back side.
This is my pertronix-installation. Easy: the black wire goes to coil negativ (-), the red one to coil positiv (+) / It's already been tested, since I started the engine outside the car...
