The wires are orange to the courtesy lamps Other wire is white. Orange is positive and ground is white. Ground comes thru the courtesy lamp switches. Front of door. If you take kick panel off you can see the 2 white wires going to switch. You can use a meter to check. Should have ground when door open and not when door closed. The drivers side courtesy lamp mounts to the left of the cover you have off. The odometer zero **** is hanging there. It goes into bracket along with vacum light overide switch. In that bracket is a round hole to put the lamp socket in
A few suggestions:
1. Always state the year of your vette
2. Invest in a AIM, Assembly Instruction Manual. Like Easy Mike suggested.
3. Invest in the GM service manual.
If you're trying to say that the interior lights stay on when you have the door shuts for a while, check your courtesy light timer (orange box under the passenger side glove box area). If you connect the two white wires, they should only come on when the door is open.

I made some test :
On LH courtesy switch : 2 wires - one black "ground" and one other that go ...
Can't find LH lamp bulb and support
On RH Courtesy switch one white wire (gournd) that go to ...
On RH lamp bulb, two wire, one orange and another white that go to...
I think that all the wire go to the same in law.
The RH Courtesy lamp and back courtesy lamp (LH is not here) can be swtich off if i turn the headlamp switch to lower the luminosity of the dashboard. Theses lamp is ON only when the luminosity switch is full UP. (sorry for my english). I don't know if this scenario is normal?
GREG dash light ctr console maybe .
