Thing is, there is no harness right now for the SSC1/SSC2 and SSC3 w/BackLit. It uses a 4-pin DT connector and Diode has not put out a dual 4-pin harness yet for the upfitter switches We have them coming in, but it'll be a few weeks out. You COULD use this harness (it just has extra connectors on it for some extra lights)
