We do not have OEM type vehicle wiring connectors but you can make a spliced connection to your 2005 Sierra's 3rd brake light wire using a Quick-Splice connector such as # SWC501915-1. These allow you to tap into that vehicle wire's brake light switch signal which is sometimes required for hardwired brake controller installations.
