Spent some time figuring out where and how many wiring runs have to be drilled in through the center section. If you have drawing OP-11 – RV-8/8A Wiring Harness Instalation it clearly shows the holes for the rudder cables, rear battery cable passthrough and two additional 3/4″ holes for wire runs. Somehow I managed to find a copy of OP-11 floating on the internet. I’m not using Vans wiring harness but I do want to know where they suggest to place holes through the center section. When the holes get enlarged to 3/4″ they are very close to the spars. Measure 50 times and drill once. Right Rear – 2″ up and 1/2″ left.
Left Front – 2 and 5/16″ up and 1/2″ right. I had not yet drilled the battery cable pass through hole.
Right Front Left Hole – 2″ up and 3″ left, Right Hole – 2 and 5/16″ up and 1/2″ left.
Left Rear – Both holes 2″ up and 1/2″ and 3″ right.
You can see that you don’t want to be low when drilling these holes.
