Hi all, new here and fairly new to the Subaru scene. I just bought a 1997 Subaru Legacy Outback with 86K miles over the weekend. I was looking it over last night and found a connector unhooked under the dash, right under the steering wheel. I hooked it up to see what it would do, and when I started the car the Check Engine light started flashing. I unhooked it, because the light would drive me crazy. I don't know if the previous owner unhooked the light, or the dealership. Anyway, the car runs fine, no hesitations, great acceleration, no strange noises. Should I be concerned about this, or is it just a bad reading from an O2 sensor or somthing causing it to flash? Any input would be appreciated.

From memory, that connector under the steering column is deliberately left unhooked - the service departments use it to hook up their OBD readers. If you do hook it up, the check engine light will flash.

Yes, what Losiho said. That connector is for checking the system, leave it unconnected. Brian
