I have a separate fan and light dimmer I was replacing to a different color. I took pictures before I unhooked on my fiancés phone. Unhooked everything and those pictures are no longer on her phone. I was able to trace all the wires but two need some help hooking everything up.

There are four sets of wires coming in the box.

Left - black and white. Not sure where these go but I think it's an outlet behind my dresser.

Second - black and white. Black is power from breaker box. The same black wire comes out of the ceiling which looks to be wrapped in electrical tape. . White goes to outlet in same room.

Third - black white and red - All three go to the outlet mentioned above.

Fourth - black and white and ground. Black goes to black wire coming out of ceiling. White comes out of the ceiling as does ground.

Ceiling has two black wires, one white and one ground.

There was also a jumper wire.

Currently I have the black wire from the breaker connected to a jumper going to thevred wire. So that outlet will work as I have my tv plugged into it.

Red Dots wires on the left
Green dots are wires coming out of second row
Blue dots third row
Yellow dots fourth
White dot is hot wire

From a distance now you have lost the pics, impossible to predict which wire goes where.

I traced them out and put it in the main post. Posted the picture with color code to tell you where each wire goes.

In the post

First, second, third, fourth are descriptions of the wire and where I traced them too.

I color coded in the picture for reference.

Some of that makes sense but at the moment there are too many variables.

You have the right number of wires in the celiing: two black hots, one for fan, other for light, a white neutral and a ground. At the wall you have what seems to be an incoming feed from the panel via an outlet (you say the neutral goes via the outlet, I would infer the hot does too) and an onward feed to the outlet powering the TV.

One would expect the neutral in, out and to the ceiling all to be connected together; the hot in and out to be connected and also pigtailed to the two switches / dimmers, and then the two controlled hots out of those to head up to the fan and light.

But I can't make sense of:
The same black wire comes out of the ceiling
when referring to the feed from the panel / previous outlet.
And it's not clear why the next outlet beyond the switch has a red and a black hot... was one half of a duplex controlled by the switch and the other not? And there don't seem to be two black hots leaving the switch box towards the ceiling.

So it needs further investigation / clarification. You might need to access the outlet behind the dresser, and double-check the situation with the incoming power feed to make sure the hot and neutral are correctly identified, coming from the same place in the same run of cable. An electrician would probably make a quicker job of it with less chance of error, simply through experience.

The outlet where the tv plugs into has two white wires, two black wires and two reds. I'll have to check the other outlet. I really appreciate the feedback.
