Okay, looks like what you've got isQuote has been trimmed, See full post:
1. a ballast, the large black rectangular thing with all the wires coming out of it
2. a capacitor, the large grey cylinder with two wires going to the ballast
3. in igniter, that little black thing with three wires in it
4. a ceramic lamp base, the white thing that appears clearly only in the third picture.
In the second picture you're holding a red and a white wire. If I'm seeing the details correctly, the white wire appears to join a white wire from the transformer and a yellow one that goes to the igniter. That's the common or neutral wire. Join it to the white wire in the lamp base. The red wire appears to join a white wire to the igniter and a red wire to the ballast. That's the hot wire to connect to the black wire in the lamp base.
The four wires you're holding in the first picture appear to be the white, orange, tan, and black ones mentioned in the spec sheet. The white is the common, joins the white wire in the outlet box you're wiring this thing to. The orange wire is the 120 volt connection, that joins the coloured (almost certainly red or black) in the outlet box. The other two are for 277 and 347 volts, which you won't have available in a residence. I'd put one of those wire nuts (marrettes they're called, officially) on the end of each one and coil them up out of the way, you don't need them.
