Weird noise after push start button?

So, I ended up installing a push start button on my car, I followed the following link for installation, http://www.clubintegra.com/board/showthread.php?t=45140

Anyway, once I try to start it, it’ll make a really strange noise, I let go of the button, try again and it starts without an issue.

Any ideas?

I will include a video.
