What Version Is My Console? Please Help!

[lufcfan]

Hi,
I have recently ordered my new Messiah ModChip from liksang.com. I was reading the instructions on how to set the jumpers. Of course, after reading numerous websites I figured that my PS2 was a PAL PS2 V4. However, today I saw that my model number ( which is 30003R ) was a v5. I seriously need help. I obviously need to get the jumpers set right. Any help would be great. If Charlie, or anybody at all is out there, Please Help. Any thoughts would be fantastic.

Ordered Messiah.
