Hi guys just a quick question. When relocating battery and installing turbo side intake do you need to drill holes in engine bay to put in place new battery holder?

When doing this how do you connect power cord to reach onto the other side?

Any help would be greatly appreciated.

Your kit should come with instructions, but the answer is yes, you need to drill depending on the kit, I had to drill 3 holes from memory. The power leads connected to to the starter and bridge across to the fuse box, via cables supplied with your preffered kit.
