I hooked up my new trailer expecting it to charge the battery while I drove. However, after some exploratory surgery I found that it had no charge wire hooked up. It did have the brake controller wir...

Well just to document the final end of my story here. As stated earlier my Expedition came with the heavy duty towing package with a 4 pin plug minus the 7 pin plug. Of course, I do have a 7 pin plug, but the installation is definitely not factory. It was obvious that the factory 4 pin harness was installed with the blue brake wire taped up inside the loom. The 7 pin harness was spliced into the wiring with crimp connectors without a charge wire.
Since several respondents have cautioned that I may not have the heavy duty towing package, I have done the following:
1. I verified I have the 7A095 auxiliary transmission cooler.
2. I verified I have the 3D746 power steering cooler.
3. I verified I have the 8005 Radiator, which is the only one available for 06.
4. I have added a Scan gauge and programmed it to monitor the tranny temperature.
5. I have added a 12 gauge charge line by tapping into the 12 gauge orange wire under the drivers door attached to the frame (yeah I know it should have been 10 gauge).
6. I have added a 30 amp fuse and relay to the passenger side kick panel fuse box in the trailer charge wire positions.
7. I need to have the tranny fluid changed - as it is original most likely.
Once No. 7 is complete and I get some free time from work, I am ready for some heavy duty hauling and camping.
