Wiring Power Windows

[agamble]

I am attempting to wire up power windows in the Comanche. Nothing is hardwired yet, as I am trouble shooting. I've tapped into the fuse box, crudely for now, which runs through a fuse. It then splits into two. I have one line powering the master control switch on the driver side, the other goes to the passenger side control switch. As it stands I can get the master control switch on the drivers side to open and close the drivers side window. Then I am able to get the passenger side control switch to window to open and close the passenger window. The problem is when I try connected the master control switch for the passenger window in. To tie them, the master control switch and the power window motor, together I have taken a third wire, which I tied into the master control switch passenger window wires, then ran that over to the passenger motor wires. When I attempt to tie the master control switch in to be able to also control the passenger window I keep blowing the fuse. If it doesn't blow immediately upon connecting the wires, as soon as I flick the master control switch for the passenger window it will blow the fuse. What am I doing in correctly?

Are you working from a wiring diagram, or are you guessing?

Guessing. I was being lazy and didn't want to take the time to find or draw. I have since seen the error in my ways and took the time to draw out a wiring diagram and found the solution to the problem. Below is the diagram I drew for reference:

 

The problem was I was putting power to the negative side of the switch, which in turn was causing the fuse to short out. The solution was I need to add a fourth wire. One for power, one for ground, one to connect the positive of the passenger side motor, and a separate for the negative side of the motor.

HOrnbrod, where does the passenger door switch ground?
