the radio interface harness part number is fast-2003 with a fast-btah connecting between that and the sub.

do I need a different interface harness?

first post and hey everyone.
There is no switched voltage circuit on the 2004 Silverado radio. You can use the FAST-2003 (or the FAST-9999), however, in either case you will need to run a wire from the blue/white wire of either FAST Harness to the factory fuse box.
