Introduction Here's how to install an electric trailer brake controller in a late-model GM truck ('99-'07-Classic; Silverado and Sierra).
If your truck came with the HD Trailer Towing Package (RPO code Z82) it will come with a "Brake Controller Pigtail" wiring harness in the glove box. These are also available separately from the dealer.
This is what it looks like. It includes a five wire harness with a connector on one end and blunt cut wires on the other end.
It also comes with a 40-amp "B+ Trailering J-Case fuse" which will be securely taped to the wire bundle.
There will also be a small instruction tag attached. Here is a SCAN of that tag in .pdf format.
