Need wiring diagram

Does anybody have or know where I can get a wiring diagram for the Passlock system & steering column for 98' Tahoe.

Any help is greatly appreciated!!!

if you are trying to put a Remote start system on that there is no wire for the Pass lock system you can have it clear from the computer some how or you can just buy a thing for about 30.00 and you wont have to mess with it go to http://www.bulldogsecurity.com/ you should find what your looking for Ps Dont Try it with out the pass lock Thing because it will turn on the Check Engine Light on it will go off in a day or too but it does write thing to the computer

Also DO NOT UNPLUG THE YELLOW TUBING THING THAT GOES TO THE AIR BAGS it can cause the just to go off at any time
