I have added fuses for a turbo timer, boost controller, and other things to the factory relay block. It is super easy to add additional circuits into them. You either need to source terminals from a donor box, or source the terminals themselves. I prefer the later and have purchased the following for this: http://www.cycleterminal.com/atc-fuse-box.html (go to the bottom of the page for the terminal strips themselves).

Best,
