I have a 2001 Chevy Blazer Trailblazer package. I’m having a hell of a time trying to find the correct t-connector for a trailer brake light harness. The brake light connector is a square 4 pin but everything I’m finding online is different. Does one not exist for the particular trim package blazer? Would I just be better off slicing in a flat 4 pin? Thanks!

 

If it came with a factory-installed hitch, I believe the wiring should already be tucked behind the bumper. You would just have to wire up the receptacle of your choice.

 

My 04 did not have a hitch, but the wiring was already there. I believe they're all pre-wired and terminated behind the bumper.

 

Even better!
