I had the dual zone. Same as the heated seat module, just without the button. I'm not sure if this would work for you. Maybe check out some wiring diagrams for it truck and check the plugins on the back of your module to see if they are similar to the ones I posted.
I recently added XLT 302a heated seats to my 301a. Before I did this, I searched a lot to see if there were any how-to write ups and I could not find anything for only heated seats so I thought I would post how I did mine. This is a big Job, very time consuming but it is not impossible.
