Forgive me because this is probably a stupid question. Does unplugging the connectors while the truck is off pose any kind of PCM, ECM, etc problems? I plan on using dielectric grease on every connector I can find underneath.

I have done the same and had zero issues.

Just put on a Magnum headache rack yesterday so have two problematic connectors instead of one. I used a generous amount of dielectric great and ended up removing the original connector from the frame and zip tying both the old and new connectors up a bit higher.

@troverman Did you do anything different with your install?

I don't see how it could. I currently have at least 18 of the connectors disconnected, waiting for a canister of dielectric grease.

From the back of the truck, right side looking up
Ok I went out today to dielectric grease the connectors in the rear of the truck. Problem was I couldn't find some of the ones that I saw earlier in the thread so I dropped the spare tire and low and behold there they were in a tangled up zip tied mess. My truck was rear ended back in November and one of the things that was delaying completion was a wire harness. I couldn't believe the body shop did something like this and I was pi$$ed. The harnesses in question still had the push in holders on them but they ignored that and just bundled it up in some kind of half assed mess. Got 'em all greased and put them back where I thought they went. Anyone who has greased your connectors could you look at the pics and tell me if they're in somewhat the right place? I'm assuming the harnesses attach to the insides of the hitch. Thanks

That second pic looks correct - mine are attached to the inside of the hitch like you show.

had to exhume this one from the grave because it’s the most relative one I found so far. Is there any reason to not solder the wires together and get rid of these connectors?

You'll want the connectors in case the tailgate has to come off. They may also be needed should a change be made to the 7 pin tow connector, like say if TPMS/Camera is added. It's been a few years since I did the install of my Ford TPMS/Camera system, so I don't recall which exact cables get disconnected, but they're in that area.

good thought. After the repair if I’m still having electrical issues, (no collision warning, cruise, or fog lights) could it be a bad module, or does the module have relearn after the battery is disconnected?

Sorry, I don't know the answer to that.

To answer you question - if the truck has all of the original parts it was built with, it does not have to re-learn anything. With multiple issues like you noted it is very likely your problem is a wet / dirty connector(s). Separate each connector and inspect it carefully. If there is any corrosion present you need to get it cleaned out. When ready to reassemble, lightly spray both the pins and the sockets with De-Oxit or something similar. Connect and disconnect each pair 6 - 10 times to help clean off any residual oxidation and to get the De-Oxit spread across all of the contact points. For the final assembly, put dielectric grease into the connector and connect it firmly.

Connect to the truck with Forscan, reset the DTCs and when it finishes that procedure make a note of any remaining DTCs. Post back here with the results.
