wiring help with switching to exhaust fan timer switch

I'm replacing my bathroom exhaust fan/light combination. Currently the light is operated on one switch, while the fan is operated by a separate toggle switch. I want to replace the fans toggle switch with a timer switch. Need a bit of help. I took off the wall plate and pulled out the wiring as best as I can to get a good look. Here is what I see:

There is a 3 wire and (2) 2 wire's coming into the box. The red wire from the 3 wire goes to the top screw on the light switch. The black wire from the 3 wire goes to the top screw on the fan switch. The bottom screw on each switch has a black wire that is part of a pigtail to the other incoming blacks. All white wires are pigtailed together.

The fan switch I bought has the following wires. A green, red, black, white and a yellow with red stripe. The yellow one has label on it that its only used in a 3 way installation.

Can someone help me hook up this fan switch? I'm not sure if I even need to touch anything on the light switch side or not but either way if someone can help me get everything connected that would be great. thanks

You do not need to touch the light switch.
  • White of timer to group of whites that are connected together.
  • Black of timer to group of blacks that are pigtailed to both switches.
  • Red of timer to black of the 3-conductor cable.

ok, having an issue with wiring at the actual exhaust fan/light unit now. I must have something done wrong. This end has 2 plugs. One plug is for the light and it consists of a blue wire, white wire, and green. The other plug is for the fan and has a black and white wire. How do I connect these to the 3 wire coming over from the switch? I must have not found the right combination yet, can someone advise? thanks

Whites to white, blacks to black, 3-conductor red to fan blue.

Edit: Rereading I may have confused you a bit. Wait a bit and I'll see if I can draw a diagram. If anything on the diagram doesn't make sense I may have misunderstood what you have so post back.
