05 buick lesabre, alarm/remote start

I have installed a dozen or so remote starts but this is the first with a data wire for alarm bypass. I have done gm's passlock so is the passkey done the same way?  I have found differant wiring info on this so could someone post  the actual diagrams. I have bought a 555g and wiring diagram says I need to hook purple wire to data at the ignition but can't find diagram that tells which wire this is   thanks   steve2003 silverado2500HD LT crew cab

Hook up to the purple wire at pin two of the data conecter under the dashdouble-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer

thanks but exactly how do I do that, do I need some sort of connecter to plug in the front and how do I know exact location of that pin2003 silverado2500HD LT crew cab

also what are the colors for the ignition wires to hook up to the pink/black and the pink wires of the 555g2003 silverado2500HD LT crew cab

ok maybe i'll explain a little better, does anyone know the colors of the specific wires for the 555g pinkignition (ecm side)- pink/black(key side) to match up to at the key cylinder or how to find which one is which. I know these are thin gauge wires and I have done many passlock ll but this is the first passlock lll and I've always been able to find the ones I needed ina diagram but now I cant seem to find specific wires  thanks for your time2003 silverado2500HD LT crew cab

Why mess around with the 555G? Get a GM-DLBP from bypasskit.com, and it does locks, trunk, factory arm/disarm, as well as Passkey III bypass, all with one piece.

yes but this is for my mothers car and my father bought her a standard starter without the unlock/lock so I purchased the 555g thinking this would be what I needed,  he bought it thinking that I could install it because I was able to do so on her '96 regal but that was differant system with wires coming from key cylinder and this one has a black control type of box with 5 wires coming from it from left to right -   purple,purple,black,pink, orange so which of these do I cut and which one do I splice into 2003 silverado2500HD LT crew cab

I suggest getting a databus module for this vehicle so you don't have to grab the OEM alarm disarm wire in the door. Trying to get from the driver's door to the inside of the vehicle is an absolute pain.Jeff
