the hard part is finding the wire color for the starter off the ignition harness
97 - 99 is yellow or purple @ the d1 spot. 00 - 03 looks the same

as is 04+ except they can tap the bcm instead conn. C1, pin 21

to get to the wires you need to remove the snap on dash cover the lower cover then the security shield. and that's where i am at so far today.
it's raining so i'm working on mounting it
