engine dying due to electric fan

Yeah that's OK.

Be VERY careful on mopars and where you pull power from.

I WOULD NOT be running factory charging system wiring with an electric fan. You are asking for a melted bulkhead and potential fire. Problem with fans is that they tend to run when the engine is on or off. If you are running the fan only with the engine on, battery is a bad spot with factory wiring.
please, I'm open for suggestions. actually, the original post is for help. and yes, with the fan on the ignition switch, it only runs when the key is on. any help is appreciated, more than appreciated. what do you (or anyone else) suggest? can the second power wire be connected to the battery as well? or does it need another power source?
