Couldn't decide if this was an electrical question or an 04-08 question.

Hopefully this wont be too long of a question, it will be 2 parts. I have an 05 FX4 that does not have defrost, TCS or a reverse parking switch. Just bought 08( I think) FX4 trim piece climate control switches w/ defrost. It also has a TCS switch and Reverse Parking switch on either side of the cig lighter.

Here are the part numbers listed on the climate control(kinda confusing for me)

4L3H-19808-BH (dtd 11/15/07)-from this date is why I think for an 08

7L34-19980-BA / 7LBA135418

So here are my questions.
Can I just swap them out? Will the plugs be the same?
Is my truck prewired for defrost?
Since the new controller has defrost and I plan on adding 09-10 Tow mirrors. I know it will require some wiring but will it work for them?

Part Two-The Switches

I have neither the TCS or parking sensor options.
I am not sure if TCS was an option in 05 but I think the parking sensor was. Would my truck be prewired for at least the sensor so I can send power to a relay instead of the sensor?
I would like to use them for my Aux lights to keep a stock appearence. I have a Hella grill with lights and KC daylighters(Thanks Lush!). I would like the switches to work with the dash lighting(not sure if are even supposed to light up). TCS is a 6 pin switch and the Parking is a 5 pin.

Thanks for any input.

 

Looking at some pics of dashs, I think the new piece is for an 07. It has all ***** and no LEDs. Unless the button control/LED re-out ones are for a specific models(HD,KR?). Depending on which part numbers one starts with 7 and one with 4.

 

Just learned it will swap out but for the defrost to function I have to change to a fuse box with defrost option.

 

The Button control/LCD display units are for the Auto Climate available in the higher end models - Lariats, KR ...

 

Thanks. Funny, not 5 secs ago I read the owners manual and saw it. I guess it really pays to read those things. Didnt find the mention of the TCS option in there.
Aren't you from Destin?

 

Grew up in the panhandle, I lived in Destin after college from 06-08. How'd you know that?

 

I'm not a stalker, I swear. lol Think I saw it in the Regional forums and your name is pretty unique. I live in BWB right across the bridge.
