I've seen other posts where users are putting a single pin weather pack connector on each aux switch wire under the hood. I wanted to go a little different direction and have one connector for all 6 wires. No labels to worry about, no having to pull up diagram when adding things, all 6 wires in correct order in the connector.

My first aux switch project was BD A-pillar lights from @4x4TruckLEDs.com . Nice kit, had all the wiring needed, so I did my install originally using the provided scotch lock as I hadn't decided on the 6 pin connector yet and I was anxious to get the lights installed. I bundled up the extra wire and zip tied it in place.

After my 6 pin stuff arrived I went about changing the connection out for the 6 pin. When I installed the lights I taped the 6 switch leads together in correct order of the switches.

My original plan was to make a short harness to go from the 6 pin connector to the 2 pin connector on the BD light harness, but I realized this was just adding another unnecessary connection since there was plenty of wire in the BD harness to make it to the 6 pin connector and the ground without adding a connection. I removed the 2 pins from the BD Y-harness connector, and inserted the positive pin in the 6 way connector. I cut the pin off the negative side and replaced it with a ring terminal to go on the grounding point.

They make plugs for unused slots in the weather pack connector, but they are backordered everywhere. I cut a stub piece of scrap wire for each unused spot and put them in a seal to plug the holes.

You can always change the position of the wires on the downstream side to change which switch controls the device, just pop the pins out of the connector and move them to the new location.

I set all my upfitter wires to single pin weather pack connectors that way to change switch position just unplug and move.
Yep. Said that in the first paragraph. Offering an alternative.

Is this what I should get?

Looks great! Almost like it came from the factory that way, if it weren’t a Ford. 🤡

I looked at that kit, my only concern was that the terminals are for larger wire than what most of the factory wiring is. I ended up buying parts and pieces from another site, in bulk. I'm happy to put together a kit for anyone that's interested. I had worked through the cost before but don't have it handy at the moment. If there's interest I can work up a price.

Wow. Pretty beefy set up. I like the old school crimp and heat shrink myself....

I have enough extra parts for 8 kits. My cost on these is $11.27. Asking $25 per kit, shipped (US). Kit would include everything needed except the crimping tool and the pin removal tool.

Contents:
8 ea Green seals
6 ea 16-14 AWG female pins
6 ea 16-14 AWG male pins
1 ea 6 pin connector female
1 ea 6 pin connector male
6 ea 20-18 AWG female pins
6 ea 20-18 AWG male pins
10 ea Grey seals

Very very clean. Nice work!

I had thought about using 1 multi-pin connector, but since this was the first time I used WP connectors I decided to go with the less thought approach of a couple single connectors. One of the unknowns was plugging the unused pins. (y)
I may switch to a single multi-pin connector, as it's much cleaner looking.
The main reason for me to use WP connectors is to make sure each accessory I add is easily removable for maintenance and repair. I don't want a technician (or me) to have to cut wires and ties to pull an accessory just to get behind it. Everything gets a re-usable connector near the mounting place (some pieces still come with hard-wired leads) and at the termination point.

I got a kit that included a crimper that crimps both places on the WP pin at the same time. It worked well enough for me, but I've never used the tool where you crimp each point separately. 🤷‍♂️
