i think you are referring to the scans we have of the cluster power map, but the post im thinking of is in picture form. This one isnt as detailed as the one the diodes are circled in, but points you to the power tracers in the ribbon cable. Basically where you ended up testing for power.

as long as you got it done thats what matters. In that thread i was referring to earlier……

one trick before taking anything apart is to simply whack the dash above the cluster and most of the time the bulbs will Come back on. Its just old filament 90 percent of the time. The only time anyone needs to troubleshoot a failure on the board its usually self induced (cluster modifications tend to burn tracers and blow diodes if done wrong). If they just dont work on a stock cluster, bad bulb. The reason is there are no capacitors to fail in line. Just a diode and those are not susceptible to time like capacitors.
