2 Questions, need help!! 1998 OLDS BRAVADA
 

I have a 98 Olds Bravada and my first question is: Is there any relays behind the Instrument cluster or near the kick panel for the HVAC blower motor?
Second question, does anyone have a wiring diagram for the ignition switch harness, im looking for the yellow wire that is at the end of the harness that is on the gray connector on the side that you have to bolt to a cluster underneath the dash?
