PG-38 says fuse #19 (10A) supplies the combo meter (is that the same as triple-gauge or is it the tach/speedo?).
PG-42 shows the Ignition Relay on the back of FBJ/B that turns on fuses #3 & #4 (and #2). Relay is turned on by BCM (terminal 82).

I'm tired of looking for now.
The thing is the ignition switch appears to be working just fine, it def has power.

Page 38 is referring to the constant on power source that is supplied to the combo meter, this circuit is unaffected as I tested it last night as it should be. I was using the ACC circuit to wire my gauges. This circuit is working just fine. Which further proves that the fuse block does have power.

Page 42 - I missed that! It also looks like Pin 82 also turns on the blower motor, so by that logic if my blower motor is working then that circuit is working. And I believe I remember having to shut off the blower motor last night to save battery while I was running my tests. It also makes sense that I didnt see any airbag lights once the car was running (I started it with both the steering wheel and passenger seat removed).

However if you look at page 42 this relay also controls Fuse 3, which in turn controls pretty much all the other dash components. I know for a fact that I have power on this fuse. But it also appears that this fuse can pull power directly from the BCM? Not sure what the reason for that is, seems kind of backwards that you could have an unfused connection between the BCM and its end components (as seen on page 52)

Thanks for all your help SouthArk, passed right over page 42
