[&:]my 2005 trailblazer has the towing package and i now have a trailer with electric brakes so need to install a brake controller. I have gone to the dealer to find out where the plug is located but they were out to lunch in more ways than one.
Has anyone installed a controller , can you tell me if there is a plug or do i hardwire this box ? Thanks alot

 

[&:]the forum gang didn't help but i found a trailer sales that knew what i was looking for. The wiring for this truck is rolled up and tucked behind the the left side panel. It has to be hot wired - there is no plug like one place told me. Maybe someone will be helped by my search.
