Welcome to AF!

Your duplicate post was removed, thier was no need to post another thread with the exact same thing.

Try this link, look at the wiring diagrams .

Hope that helps

ps the grey wire is the dimmer wire.
use a voltmeter or test light to find your constant power
and keyed power wires, the lighter can sometimes be used for the constant power.
