Just got my pocket n harness in
 

ok, i just got my best kits pocket and harness, the pocket is a scosche. i looked at the harness. i have a few ?'s still.

i plan to install my head unit maybe next weekend. one of my questions are: is this that simple to install? like taking out the factory radio then wiring using the harness. it says all this stuff about where all the wires go and it's just confusin the hell outta me. yes i've read the site about the install on the protege 5 already. but im still iffy about all this. i dunno what im really askin for here. . . maybe a few tips on what to do when i do it. thanks a lot.
