Hi Guys, Well im absolutely loving my JDM spec Impreza, although since owning it the orange engine light constantly flashes as soon as i pull away in any gear from starting the car. If i run on idle its fine.. also before starting the car the fans go on and off and continue to do it.. ive done some research and have found out this may be caused by two plugs being together.. however thanks to some rubbish alarm installers in the previous years it would seem they have bodged and cut most of the wires.. what do i do.. pic is below.
