fu chip install-? on how goes in truck computer

[wckdpowerstroke]

gonna get it installed as soon as the weather breaks a little.

So my question is-
When i install it will the chip go inside when putting it on or will it sit outside the computer?

I dont want to mess up like i did with the programming of the chip i had it outside the programming box and it wouldnt program, so i dont want to make the same mistake when installing it

Thanks
Mike
