Ok, I went to buy a transmission from a junk yard and I was told that elantras from 6/1/99 and up have a 6 wire harness beside of the transmission dip stick. And I think that my 97 tib has a 4 prong. So what is the difference or does the guy at the yard just not know what he is talking about? And what is the harness, and is there anyway to change a 4 to a 6? Thanks
