Audio Systems: 2003 Chevy Impala; New Car stereo install, cadence amp, 1997 ford taurus

Question
I just bought a new 2003 Chevy Impala, last car was totaled from an accident. Previous car was a 1997 Ford Taurus. I had a Pioneer head unit with to kicker 5x7's, 1000w Cadence Amp, and 2 Cadence Beast 12's. Im trying to hook them up ASAP to the new car. I don't know exactly how to do it, but i have good people who do. Now, they arent professionals and it is something that i'd rather do myself, but im not trying to mess anything up in my new car. Any suggestions? also, can i still use my stereo harness from the Taurus in the Impala?

Answer
this car is deferent and you need a new harness with protocol interface
if you pull the radio out of your vehicle  the cluster stops working or goes crazy  you lose the chime noise from the door open
and you lose the key on ignition warning  you also don't see if there is gas or not in the car
this interface is about 100 to 140 in local car audi stores here is where i will get it from and you can read more about it
