I bought a 2009 Tahoe that does not have a REAR window wiper/washer switch on the turn signal lever. And it also does not have the rear wiper connector taped on the wiring harness opposite the tow/haul connector. Obviously somewhere along the line someone made a change and didn’t carfax it. Anyway, I need to know what wiring harness to look for in order to wire in a different switch with the rear wiper control. I couldn’t find one on a couple parts sites or search engines. The switch with the rear wiper control is readily available. I just need the harness with ALL the plugs and jacks.
