where did you get this info?do i need any special modules?

you will need a 555L or 555T which is a module that emits the signal from your key to the ign. And i believe your door locks require a 5 wire (relay)

do you know where can i get the digram to show where the wires are at on the 2003 silverado?Ive herd of directtech but you need a pasword to get any info
