Gauge ?

OK I have my three gauges and i was wondering if i could connect all three of the black wires and use one ground and do the same with the power wires? As of now I am using a fuse to power my boost gauge. Or do I need to have three different grounds and power sources?

no they dont need there own ground or power, however you need to put a fuse before they split to each gauge, the ground doenst matter.

so i can tap the ground wire and just run them all the same wire? but i dont know if i that would have to use different power sources because i don't think that one fuse can handle three gauges. Or could i connect all of the power wires and run them to the same fuse as one wire?

yeah run one wire into fuse, the same u would wire a small amp...use an inline fuse.
