when i reverse my z, the needle goes backwards and the power steering light comes on and stays on,the instructions that came with it are both different.one says this way, the other one says there way.
a little more information..... a little more info on what 300kmph speedo you have and what instructions you have would be nice
its 300klm face i got through gb from fleet, i drove the car tonight and every thing is back to normal it must have fixed itsself.
