Ok, I've looked at many posts about the upfitter switches and pass through wires - the good news, I found all the wires needed. I'm new to auto electronics, so I'm not sure what to do with these Blunt Cut ends of wires. Do I just cut off the black end, or cut into it and splice it there, or is the Blunt end some sort of connector? I appreciate the help. The pass through wires on the 2018 F250 are already very short - cutting them shorter isn't gonna be fun.

Thanks.

The black covering on the blunt cut wires from the upfitters is shrink tubing, to keep it insulated from the others. When you want or need power from an upfitter, choose your switch and corresponding wire, strip off the shrink tubing, then connect the wire to the circuit you want to power.

 

Ford Didn't do us owners any favors with how Short these user wires are!
Especially the ones under the passengers kick panel

 

 

But 3 or 4 more inches per every unit they sell is...

Ford has a web site for them

 

 

That doesn't look like a Ford website.... Why would I have to join for "30 free days" of downloads. Does anyone have a link where I don't have to join something to get the info?

 

 

This link may work better for download

Yeah, should be at least 16 gauge. I just used the brown wire. For sure it wouldn't fit in 18-22 gauge connectors. I used the next size up 14-16 connectors.

 

Thanks a bunch!

 

 

On the pass through wires, I heated up the ends and the covers slipped right off. I then used connectors to splice my wires in.
Simple and reusable, I find they work well for low amperage applications.
