Hi. I am having major problems since trying to install new radio after removing old one. I shorted some wires between original radio harness connector and new stereo connector. Now the wipers, power windows and original radio will not function. Checked all fuses at kick panel and under hood and all are working. Would someone be able to upload the wiring diagram for this model. Thanks so much.

 

Radio diagrams are here, 2004 had 3 options: Ford Ranger Radio Wiring Diagram

You will probably need a shop manual for 2004 Ranger, an EVTM(electric vacuum troubleshooting manual).
You can sometimes download them free, or buy them on ebay

You problem is most likely in the Smart Junction Box(SJB), that is where the fuses are in kick panel.

Wiper relays are in the engine fuse box BUT.........are controlled via SJB
All the power window stuff is in the SJB

Here are 2 power diagrams for 2004 Ranger
