I'm looking to swap out an 07 SS cloth interior into a 03 Trailblazer LS. I haven't had a chance to get into the 03 yet to look for a wiring harness. Does anyone know if the 03 Trailblazer LS's were wired from the factory for power seats for a plug & play swap? Mainly wondering about the driver's seat as the passanger's is manual.
