Ok, my 92 325i has a big round 20 pin connector (i think it's 20 pin) anyway, I was planning on getting an obd reader, but am not sure what to get.
I am told i need an obd1 reader and that an obd2 won't work, is this true?
And if so what is the correct one to get?
If someone could scan ebay for the correct one i would appreciate it alot.
Thanks.
