Custom dash gauges 99-07 silverado/sierra...autometer, racepak, etc...

The power and grounds on the gauges are pretty self explanatory.
pin21 on the green(or red) is for the speed sensor to connect to a speedometer
pin10 on the green(or red) is for RPM to connect to tach
pin54 on the green(or red) is for fuel level...
for oil pressure you'll have to install a sending unit somewhere since the pcm has to have oil pressure signal to function. you can't "tap" into it.
same for ECT. you'll have to install a sending unit somewhere since the pcm has to have the stock sensor to work.
