Welcome from Austria. We love pics here.
Try searching the Electrical & Audio forum. There are tons of information here.
Get a wiring diagram for your truck, you don't know if somebody already fiddled with the wires.

I'm getting mixed reviews from other sources some are saying that an 84 carb an 87 tbi wiring harnesses won't work ??







An what's best the way to bypass the dual fuel tank switch an just use the one tank? Can I just tape up the wiring from the right tank and use the left tank ??
