Is it a cap and coil or does it look like a flour. ballast? The cap and coil are pretty straght forward. I have wired 3 of them w/ no problems. There is usually a diagram on the top of the coil, but basically you tie the neutrals (white) together. Black from the outlet goes to the primary hot (usually labeled, if it's a multi tap, use the wire labeled 120). From there, the secondary hot goes to one terminal on the cap, the other terminal on the cap goes to the black on the socket. I can take a pic of mine if you like. LMK.
