2003 Sierra Keyless question

Hey guys

Im about to do a 2003 Sierra Diesel with factory keyless and gonna add a remote start and use the remote for the rs for the keyless.  Is there an easy way to connect the factory keyless to the aftermarket remote or would i have to go about hookin it up as if it didnt have keyless?

Thank you

Chris

tou dont want to add to factory remote cause you are limited to 20-30ft range use a bypasskit.com pldata and gmdl4 and you cant get any easier youll spend about 50-60$$ but itl save major time if you cant get the bypasses let me know

 The Tach wire is easily hooked up by removing the guage cluster. Just undo dash by pulling the trim at the lower right of the stereo. Once this is removed, four 10mm bolts hold the guage cluster in place. Just pull it out, turn it, and set it on the dash, with everything still plugged into it.  The tach wire is white. (should be soldered, in case of future corrosion)

The data wire for the door lock module is purple, and can be found on the diagnostic plug at the lower right of the steering column. There are no door lock/unlock wires to speak of since this is all run through the computer.

You will also need a Passlock 2 module. This will allow the remote starter to bypass the passlock system, and start the truck. It will have to "learn" your code, so hook it up before anything else.

Don't forget the Glow plug wire from the remote start.

Just did one of these yesterday, and they can be involved until you have been through the whole process.
