Hac Micro Taxi Meter (is this how it should look)?

Hi to all,

I got this meter powered up and it just displays whats it the picture!

My question is, is the display correct and parts missing because there is only the power connections made and NONE to any other pins sensors etc?

BTW I am putting in 9v as 12 seems to make the LEDs way too bright, and the meter has a light sensor on the front which works OK and darkens it in lower light.

Anyone know?

Thanks.............Al
