So I guess, if that switch has 4 wires it would work without adding the jumper? Does your switch plug have 4 wires? Thanks Again!

I never looked, because I didn't know about it then. I have an XLT, so maybe the lower trims didn't get it would be my guess. I don't think FX4 is even an option on XL, and I don't think on STX either.

When i replaced my 21 PB, i was ordering one but the dealer had the one i have now. It didnt have FX4 or tow mirrors but it was here vs waiting.

I am curious about the wire because i can't see ford going with differnet harnesses for a $1000 option. Maybe different trim levels.

I am going to order the swtich and give it a go.

If you get to the point of having to install that jumper, let me know. I have the parts you need for it
