OP Drawings
You could get the Van's OP drawings ahead of time. If you go to the Van's LIST and search for "OP-" you should find a bunch of plans for electric, fuel and oil routing. I see that you have a RV-14 so some of the plans may not work well, but you'll get the idea. If you buy the Plans CD from Van's the OP drawings are on it (at least they were for may RV-7)
