72 Lemans Cluster Question

[Lemansport]

I have a late production(5/72) that I swapped from lights to gauges. The gauges all work with the swapping of the one wire for fuel gauge/gen light. The problem I'm running into is that the brake light is on faint and glows bright when you have the high beams on. So I did just a little checking and it seems this cars iinstrument cluster plug is different from what I can find on the 70-71 wiring diagrams.

Does anyone have the 72 only Lemans/GTO wiring diagram?

Thanks

it's part of the factory Chassis Service manual which can be obtained from Pontiac vendors. I know of no online free service and I also have only 70 and 71.
