Default 91 Caravan 3.3 liter wiring diagram

Does anyone know where I can get a copy of this wiring diagram? I am having electrical problems associated with the cooling fan. Seems when the fan comes on it draws too much power and is burning out the fan moter. I got a replacement fan assembly and when it quit working (worked once then quit) I got a warrenty replacement on it and now the same thing happened on the replacement. I am suspecting possibly a problem with the fan relay and or with the voltage regulator. I am needing the wiring diagram to isolate the problem area.

Well I take it you were not able to find this manuel with the wiring diagrams. I may have found the information I need however from another source, it is just a crude diagram but may be sufficient.

Well I have finally resolved the issue. The problem with the fan working for a short time then burning up was due to a manufacturing defect in the after market fan assemblies. The plug connector on the new fans had the notched end reversed, when I hooked it up matching the notch on the fan assembly with the plug it was causing the fan to run in reverse. When driving down the highway with the fan in reverse it created drag on the moter causing it to burn up. The company I got the fan assemblies from has been notified of this problem and they have got the company to do a factory recall on the fan assemblies.
