So I just recently bought an 08 trailblazer lt and I need to put a 4 pin trailer light connection on here so I can pull my boat but I can’t figure out where to splice in the wires. Can I co it at the 7 pin connection or do I need to wire it the the tail lights?

You don’t have to cut anything. Most auto parts stores should have an adapter that will plug into the 7 pin plug converting it to a 4 pin plug.

I had the same issue. I bought a plug like the one pdcomm showed, plus a 12" 4-pin extension. Plugged the extension into the plug, zip tied it in place, and covered it with some split plastic wire loom. Works like a charm!
