Did you use any harness or did you just straight clip the factory harness and wired it on to the stereo harness? Appreciate the video it helped give some context
Sorry for the late reply, but I used an adapter that connects to the factory GM radio connectors, and converts them to bare end wires that you can solder or splice to the aftermarket radio connector. I also needed the class 2 data bus interface in order to keep the door chime and other functions that were stored in the factory radio. I assume you have a 7th gen 04-08 Grand Prix like I do so here's the exact product I used: www.amazon.com/gp/product/B001XOBU4C/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&th=1
