Installing power locks on 2000 toyota corolla

[yot065]

So I'm trying to install automatic locks on my 2000 toyota corolla.. problem is after i took off the door panels, there a plastic tube around the rod for the lock [its to prevent slim jims]... how can I bypass this piece of plastic? there is not enough room to cut it off easily. its almost sitting right behind a panel so its hard to get to... any suggestions from people that have worked with this?

attach the power door lock motor as far down as possible... i've seen them attached directly to the latch itself...
