What do I need for flashing a stock LiteOn 7 drive?

I've read on it. I'm really low on cash, I read that you NEED a Probe, but do you NEED the connectivity kit? I can power it from the 360 and hook a SATA cable up to my motherboard with no problems. I already hooked up the SATA cable once and ran JungleFlasher and it detected it.
