The lights for the instrument panel on my 02 are not operating right. Sometimes they work, sometimes they dont. There's no flickering when they do. I've inspected and cleaned ground points G101,102, 104,and 108. All other lights are fine. 4 way flasher is fine. No CEL or stored codes. My next move is to remove cluster for inspection, and check for power. I'd appreciate it if someone had info on what pins on the connector are the +12v and ground to help fix this this problem.
The IPC light comes from 2 blacklight tubes at the sides of the cluster (1 per side). They require high voltage and there's a special power supply just for that, attached to the back of the IPC.
The IPC has several connectors, it could be that one of them is not fully seated.
My IPC is functioning normal. It's the lighting for the speedo / tach and gauges that are out. The HUD is working as well. My next step will be to check the connector, pins A8, B13, and B15 for continuity, and pin #86 for voltage. Thank you very much for providing the info.

I haven't taken it apart yet. The lights are now working normal, so I'm hoping it's just a loose connection. I'm going to add a new ignition switch and hyper flash harness as well. But I have to plan ahead because I'm also disabled and jobs like this can be more difficult than normal. I will write a follow up when I do the work. Thanks for the diagram.
