if you have done all other connections right you can go on. If you have a black wire where a red wire should be it doesn't matter. it is useful for debugging a circuit tho

if you have made the connections like you are supposed to (I think you have) you should place the chip in like so (scroll down) http://www.societyofrobots.com/member_tutorials/node/66
if you haven't done the connections right, redo it! don't take a chances.
