Ok, so i have a 2001 vx series 2, and i have just changed the headlights to the vz monaro headlights, i havent put the bumper on yet or the fog lights or anything and so all i have changed is the headlights so far..

Now for the headlights, the plug that went into my vx headlights had 6 metal things which to plug into the headlights, and my vz monaro headlights only have 4 metal things... but the plug is the same size and it fits correctly, headlights work and everything...

Now when i turn the car on, it comes up with Service Error, and then it beeps and then all the lights come on the dash, like the abs, oil, almost everything comes on...

What could this be? and how could i fix it? do i need a different plug for the vz monaro headlights?
