1998 Gmc "convenience Center"

[tnt.lee]

I have a 1998 GMC SLE went out to start the truck this morning my radio, door locks and 4wh 2wh indicator lights dont work, checked all fuses swapped relays and did visual wiring checks in the door joints does any one know where a common point to these systems are? The diagrams that I have downloaded seem to show common point being the convenience center, is there a ground point or common power point i can trace?

My 06 had these problems, I cleared most of them up by continuosly tapping on their faces...
