I've done many swaps using the under hood fuse block method for wiring using 99-02 engines and harnesses, but this is my first time using and 2003 DBW setup. The under hood fuse block is a little different as I found out yesterday when trying to start it using LT1swap.com as my guide. My question is does anyone have the wiring for the underhood fuse block method on the 2003 years? I got the pin outs for the fuse block from chevy dealership today but it doesn't tell me if the wire feeds the fuse block or if it is coming from the fuse block.

Any help is appreciated.

When you say under hood fuse block are you referring to the stock fuse block, and if so why do you insist on using it? Not bashing you just curious. I put together my own fuse block after getting rid of the stock one. If you use the schematics from lt1swap, you only need less than a dozen fuses. Dbw is only one extra power wire.
