ok, i have the wiring diagram in front of me, and it says te new radio has 3 power wires, the one with the 15 amp fuse which is for the memory, the 3 amp fuse is the bus power lead, which im confused by both of these, and then one that doesn't have a fue and that one is the power lead for accessory.

use wire nuts so if you sell the truck and buy another they just twist off..... you get the same connection with alot less work...... thats what i did

That looks about right. The 3 amp to bus power lead is new to me. Although, from what Iknow on the 2003+ gm trucks, the electronics are more advanced with a data bus that even the radio connects to. This is why the newer radios wouldn't work in an older truck even if you made them fit. maybe this has something to do with being adaptable to something like that.... i don't know. my radio doesn't have a bus power lead. Everything else looks good though.
