I bought a 2009 Silverado 2500 at auction and come to find out the entire trailer brake control module and relay were missing. Ordered this and it was at my doorstep as expected. Install was painless, no complaints. After installed got fault code C1114, then realized I had to get it programmed by a local automotive ECM/programming shop for $100 so budget at least this as the local Chevrolet dealer wanted $160

Works great. This item does need to be programmed for your vehicle. Be aware of that before buying. Some people seem to leave negative feedback on items they do not understand. Many GM modules have to be programmed for the car they go into to work correctly.

I was unaware that this part needs to be programmed to buy a local Chevy dealer before it can be used. Make sure you have your old one first. Returning mine as I don't want the extra added expense

This module was the exact replacement of the original. I took to a GM dealer after I installed so they could program the new module. This fixed my trailer brake issue.

Worked as expected 08 Chevrolet 2500 Duramax to fix service trailer brake error. Just remember it needs to be programmed. I used a generic J2534 passthrough and GM TDS.
