To make a long story short..
My boss asked for my help and without thinking I said "duh sure boss" da dope I am, and now I am up to my butt in wiring... the diagram I have attached is the best I can do (sorry), where the power comes in is standard 2 wire, that is now connected as shown to 3 wire (for 2 lights and the switch). I need to connect the exhaust fan (red circle) to the timer switch (4 coloured wires). I have access to the ceiling (where power line is coming from) straight to the timer switch, I have wiring, I have wirenuts, I even have patients just don't have a clue what wire goes to where this is my 3rd day there and now I have a hitman on standby with orders to shoot me just in case I screw up and have to go back. If someone could complete wiring diagram for me I would greatly appreciate it.

Thank you

Chase1701, I would have said "duh sure boss" and then hired the best and cheapest Electrician I could, help rendered.:D Hang tight and a real electrician will be along with good advice.

Chase,

I need some help from you please.

I need to know where you are located. What level of the NEC is required by the local AHJ?

Is this a residence, commercial or health care building?

Don

The issue has been solved it turns out the timer my boss wanted to use is not meant for this situation. But thank you donf.
