- Okay, let's see if I can do this in ascii...
- What I would tel you to do is to get a continuity meter because not all
- 4-way switches are standard-I mean some of them have line on top, load
- on bottom, and some are line and load on the sides.
- here's how you wire it, but remember to connect your travelers from the
- 3-way to the right terminals on the 4-way otherwise you'll short.

- common travelers travelers common

- Hope you can figure it out by my drawing. Also, you can
- add as many 4ways in ther as you want to. Just match the travelers.
- The contacts in the 3ways go between the common and either traveler, and
- the contacts in the 4way are weird. The contacts sort of make an X.
- I'm not even going to try to draw those. Good Luck.
