Err I posted the wrong schematic; that is the one to a 250W HPS.
Here is the sheet on yours:

K so heres the steps:
1. Leave the BLACK/WHITE wire to the CAP
2. connect all the WHITE wires together, Ballast Socket and Cord.
3. connect RED wire from the CAP to the BLACK wire on the Socket.
4. connect ORANGE wire on the Ballast (for 120VAC) to the BLACK wire on the CORD
That'll do it. Good Luck
