Fuse Tap?

Hey guys, I picked up a used Quad commander for my truck last week last night I started the install and I have a question about the fuse tap that the intructions don't clarify:

the leg of the fuse tap needs to be installed on the "hot" side of the fuse - right? I was just going to pull the fuse and check which side has voltage and "tap" that side - just thought I'd ask.

Also, are most people installing the EGT probe just forward of the turbo inlet, as close as you can get a drill in?

Thanks.
