Default ?GReddy A/F ratio gauge install?

Well, I purchased a GReddy 60mm air/fuel ratio gauge but the instruction is really confusing. I have a few question on the install of the GReddy A/F gauge. The person who sold it to me is taking too long to respond. I dont even know if he will respond. So please help if you can.
On the 5 wire cable:
1) RED is constant 12v= meaning it should be wired up on the + side of the battery right?
2) ORANGE is switch ignition 12v= meaning it should be on a non-constant 12v right?
3) WHITE is parking light= what is this? Is tis the internal lgiht switch? Should it be tapped into the parking lights on the bumper?
4) BLACK is ground= self explanatory.....
5) YELLOW is option= I think is not required

Correct me if I'm wrong, the GREEN wire beside the black connector should not have to be wired if I use the provided GReddy O2 sensor right?

There are also 2 loose wires beside the clips that plug into the data link module. RED says that it should be to the "switched ignition to power heated sensor".... Is that the primary O2 sensor wire from the ECU? The other wire is BLACK which is ground.

Your time is greatly appreciated.

The white one would be easier to connect to the dimmer switch. You can connect it to the output of the dimmer switch to control the brightness, or the input to the dimmer to have a constant on or off, when you turn the lights on, thats waht i did for my gausges, and will do when my autometer af gauge gets here. Sorry, cant really help on teh green wire, but what do teh instructions say about the green wire.

It doesnt say much about the green wire. I think that it is suppoed to be tapped into the factory O2 sensor if the provided GReddy sensor is not used. But I do plan on using the GReddy O2 sensor that it came with. I figured out the lights and power I just wired it with the turbo timer. It works fine. I also went ahead tapped the white wire to the dash light switch, instead of the parking light. Thanks for the input man. I really appreciate it!
