read through the whole forum im am performing this swap right now and ran into an issue i have a 2003 silverado extra cab short bed and i am outting in a 5.3 from a 2005 silverado.. i am trying to make it drive by cable like my v6 was so i purchased a harness from a 2000 cable driven silverado. one of the connectors under the fuse box does not match, it could connect if the key ways were cut off but i dont know if it would still work. so should i cut off the keyways or go through the hassle of switching the entire harness to dbw
any help would be greatly appreciated thanks

You should have got a harness to match the motor and then found a P59 computer with IAC drivers in it to then make that P59 DBW computer into a cable computer. There is a small write up on here for what wires need to added for the cable swap.
I wouldn't cut the connector to make it fit, more than likely the wiring from 2003 is not the same for 2000 which your harness is from. The wires in your harness may not control the same things on each pin as the 2003 fuse block.
