Which OBDII to PC cable?
 

Hi all,

I need help,
in my country mechanicers / auto electricians are not familiar with OBD kind tools, you can only scan your car at local dealer who asks 140 UK pounds for only scan (reset warning lights are not included this price).
as you understand I decide to buy hardware which will help to connect car to my laptop.
does any of you know which cable I should buy? and which software I have to use?
by the way my car manufactured for Japanese market, is there anything that I should calculate while buying cable? (such as pin number 16 or ???)
vehicle ecu protocol which will communicate with scan software???
anyway I am totally confused please help me, in brief
1- which cable?
2- from where (online shop website)
3- which software?

cheers
