Chevy Electric Brake Port

[DTangstrom]

Does anyone know where i can find the plug that accepts my electric brake controller in a 2005 Chevy Silverado 2500HD.

I think there should be a plastic box on the driverside fire-wall down by the floor. It should have a lid w/a plastic nut in the center. pull the nut off then the cover. Plug should be keyed so it will only fit one spot. Hope this helps.
