I've made a blind surround for an ikea blind. Aiming to do the whole van eventually. I plan to fix the surround straight through the front by cutting and lifting small sections of carpet and fixing self tappers into the van body (well that is what I'm hoping to do!). I'm a bit worried about catching cables behind with the self tappers that might run from front to back. I have a skyline roof fitted if that helps. Are there any main wiring looms that run near these fixing points? Any help appreciated!
