2003 Chevy Suburban Info Needed

I have a 2003 Suburban coming in next week, have Pldata for bypass.  Only concern I have is the door locks.  In all the diagrams I have found, it says to refer to directfax #1601.  This Suburban has factory rke.  Any one out there have the info from directfax 1601, or have the information on hooking up door locks?  This is not a base model.  I know I could use the gm interface for the locks, but that is too costly.  Any info would be greatly appreciated.

Setting up the door locks and disarming the factory alarm can be done with out spending more of your customers money.   If anyone out there has the directfax #1601, please email it to me, or post it here.

Thanks for the input, I have ordered a GMDL 4.  I have seen a post in another thread that said you can use a - trigger on a plug at the back of the BCM.  And the alarm disarm was easy also.  But like you stated, not worth the trouble.  Again, thanks for the advice.
