I installed these today on my late production 07. The instruction states that if installing on a post May 06 production date, to use the adaptor plugs. When I did, the turn signals didn't work. Troubleshooting revealed that my wiring (production date 5/17/07) was a combination setup. The 'upper' bulb plug uses the adaptor and the 'lower' bulb uses the Tahoe plug. The 'upper' plug operates the inner vertical LED strip, and the 'lower' plug operates the outer strip. I was surprised that only the inner vertical strip illuminates for braking.
Both are lit for running, and the outer blinks for turn/hazard. I verified this with their Tech help line.
I expect I will add one of the flexible Oznium LED light strips noted in the smoked tail thread.
