Have you done that? I am thinking about adding it onto my 2013 Equinox. No heated steering wheel option that year yet and I think it would be much more difficult, close to impossible.
I did. The problem though is that Encore or Silverado have heated steering wheel as option that year. So they just added an available option themselves. Equinox didn't even offer it as an option that year. It will require a lot more work probably. May be able to get their wheel and clock spring or may not...No factory heated steering wheel in the 2014 LTZ either.
I live in southern AZ so heated anything is low on the must do list.
Did you read the link in post #3 for the Buick Eccore?
The is also a Youtube video for an install on a Chev Silverado, do a search.
If you want it bad enough there is some info out there.
