[ad#block]Electrical Question: I have to replace a bathroom ceiling exhaust fan with two switches  for the fan and light, and a third leg continuing on to light the vanity.

• I wasn’t paying close attention when I was taking the old one out.
• Now am not sure how to put it back together.
• In the picture the switches come in on the left, the other circuit continues out on the right.

Thanks! JP.
