Guys - I have maxed out my electrical brainpower and can't find an answer specific to my '75. Can a kind sole out there please give me the answer?
Red power wire is switched, yellow needs to stay hot. Thanks in advance.... |

S11 shows a red 4.0mm (~AWG6) going in, and a black/red 1.0mm (~AWG18) coming out. Red/Black also splices to a 0.5mm black going to the clock (if you have it), the seatbelt warning system...and red/black to the interior light.
The bigger red wire is one of the four Gang of Red that's attached directly to the battery. So if you tap it upstream of the fusebox (red wire) ensure to drop a fuse in it. I never understood why VW/Porsche ran the Gang of Red without a fuse at the battery...<shrug> Edit: BTW, these are all per the 1974 wiring diagram. |

(IMG:style_emoticons/default/agree.gif) no fuses at all upstream at the battery is not good. I personally would run a new wire (circuit for your use) from battery and fuse it. Then go from there to whatever you are trying to power. |
