Power windows/locks

I have a 89 Dodge shadow, and was wondering if there were connectors in the car for power windowns and stuff. I have a 90 plymouth sundance with power windows and locks and was hoping to convert everthing over. So basically Does dodge allready have the wiring ran through the body of the car and i just have to plug in the switches and stuff, or do i have to run ALL the wires? Thanks.
