You should now have a nice Heated Steering Wheel installed and functioning in your Expy...an option Ford should have had available, but you will now be able to utilize/enjoy.
And you will have a very uniquely mod'd Expy to boot
Currently, there are not many 2017s on the road with this feature.This mod will probably work very easily on 2015 & 2016s...please post back here when you try it.
Modding a 2018 appears to be even cheaper...it looks like the 2018 F-150 steering wheel is the same for the 2018 Expy...you will still need the HSW, HSW module, wiring harness, and HSW clockspring, but at least you could save some $$ by using your Expy airbag. Please post back if any 2018 owners update/upgrade their non-HSW Expy's...I know the HSW is an option on the 2018 and up Expy, but I'm sure not everyone selected that option when purchasing.
