Review on 📻 PAC OS5 OS-5 Radio Replacement Interface with Onstar & Retention, Black, 9.00x9.00x1.90 by Duane Hayes

This could be a good harness/module. But I believe this item may have caused electrical problems in my 2011 Impala. I got error codes, checked them at a good shop in town and they said the car was fine. This led me to believe that this was the case. unit revolution. Among other error codes I received "Service Stabilitrak", "Service Brake Assist". For example, faults in the transmission control unit (note slippage / slightly rougher shifting). Eventually my entire dashboard/cluster went offline. I had a backlight, but there was no speedometer, no fuel gauge, no temperature gauge, no speedometer. The check engine light also came on. After the car sat for a few days, everything worked like magic again. It took me a heck of a lot of time to find a good wiring harness/module for my machine that wouldn't give false trouble codes. While I can't be 100% sure it was that particular product, I'm pretty sure it was. I suppose I could drive without anything on the car's wiring harness just to make sure the errors come back. But to be honest, I really can't take my whole center console apart to be sure. I have since bought a harness/module from a different brand. I'm considering buying a whole new system. nothing but an absolute headache.
