Dash wiring help

[myquestoyota]

I have a 77 FJ40 that has never given me any electrical issues until now. I have some of it sorted out but don't have any gauges. I have checked fuses and grounds but not sure how to check the plug into the gauge cluster. Any tips? Wiring looks factory with no butchering.

So did you use a meter to actually check the fuse - they can easily look good but be bad. Then there is power across the fuse - 30 cal bore brush will clean the contacts. The back side of the fuse block often gets corroded or connections get loose.

With the wiring diagram you should be able to figure out the pins and what they should read, voltage/ohms sort of measurements
