Do you have one for the positave and negative light terminals for the 2006 Chevy trailblazer radio? I'm trying to switch to LEDs and that's the only one I don't have

Pin outs for a 2004 trailblazer with 5.3l at the body control module and engine harness connections if possible. Thank you

Check over on gmtnation.com the moderator mooseman has the link for the service manuals and wire schematics. The link is located under his signature.

Good luck!
