4-Way and 7-Way Connector Recommendation for a 2003 Chevy Trailblazer


Hello, I removed the top cover from the plug on the 2003 Trailblazer and plugged the new Curt wire harness into it. However, now the plug does not snap into the bracket. The hole is to big. The top cover that I removed was what twist locked into the bracket. Do I need to get a different bracket? Just tie wrap it? The picture is w/o the harness attached but you can see the bracket hole is to big for the plug now. Thanks,


Expert Reply:

What you have is the twist lock style of 7-way bracket on your 2003 Chevy Trailblazer. If you want to use the # C55515 you will need to find a way to secure it with zip ties.

Or you could go with the # HM40920 as this is a 7-way and 4-way connector that will plug into your harness and can use the twist lock mounting bracket.
