I'm not familiar if it's in all later GM cars or what, but this wire (borrowed from this post: http://www.60degreev6.com/forum/f97/...build-t40912):

If you move it to a terminal with battery positive it will trigger the fuel pump to turn on as long as that wire has voltage on it. It will make a small spark, but nothing to worry or get excited about.
