before everyone says search i did. im looking into install an autometer full sweep electrical boost gauge. my question is which wires should i hook it up too? also id like the gauge light to turn on only when i turn the switch for the rest of the gauges. thanks again guys.

 

Try https://www.evolutionm.net/forums/ev...m-reading.html. It includes a diagram of the fuse box with labels, etc. It helped me...

 

i think I've seen a wiring schematic floating around somewhere
