Wiring for power windows, locks and mirrors... question.

[Cadee]

I have a 93 W250 that did not come with power windows, locks or mirrors but, i got some doors that have all of these and all the motors work. The wiring is in each door and i got a whole wiring harness, that goes under the dash and then to each door.
My question is, did Dodge install all of the male/female ends under the dash so that i can just plug in the harness i just got and then run the other ends to the windows, locks and mirrors.
Thanks.
