Review on ACDelco 20904439 Original Equipment Continue by Clayton Morris

I saved over $100 making it myself. 08 2500HD Silverado. Relay in the left rear wheel arch on the inside of the truck frame. Once I found it, it took about 15 minutes to install. Happy camper. Ordered a part for the second time. Not the part's fault, but where GM placed the connection. Above the L-wheel where dirt, mud and water can contaminate the electronic connection. I will try to seal the connection with tape to prevent contamination of the elements.
