I am currently trying to smog my 1998 V70. Took it to a smog shop and the tec said that he could not link up with his diagnostics. Took it to volvo and they could not get a link up with there top end computer. Said may be the obd II wiring harness. Any thoughts on this and if so does the harness go from the console all the way to the brain or is it a short run under the console with a connector there.
