    the fifteen amp fuse is going to be your power source that runs through the ignition swicth while the three amp fuse is your memory ie. clock and settings this will always have power to it while the other should only have power when your key is on

    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.

    okay so I had the first two backwards.hard to tell without looking at them. but the acccesory one( I guessing Its blue) is going to be you power antenna wire which is so you can tie in your amp, to the stereo so that when you turn off your deck the amp also turns off and vice versa, you may or may not have to tie it into your changer depending on how it hooks up, I used to have a pioneer changer that was turned on and off by the stereo but had to have the memory power to it to keep the disc at the point where you turned it off good luck hope this helps you

    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

    it actually has a separate power antenna lead which is blue, the power lead is red, and i dont have an amp yet. so i dont worry about the red wire on the radio?

    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.
