Wiring Novice Question

Can I take three wires and twist them together and solder them into one larger gauge wire? I have three Cobalt Digital Autometer gauges (Voltmeter, Water Temp., and Oil Press.) and they require you to tap into the white dash wire. I guess it's supposed to be for lighting. Thanks! Ethan

Yes and it doesn't need to be a large gauge wire for lights in three gauges.
Wire to dash lights is grey, not white.

Re: Wiring Novice Question

You can certainly do it that way (star connection) or run the last terminal to the same next one on the neighboring gauge and so on to the third one working your way back to the supply of power (daisy chain).





If you are able to put your own wires to a terminal stud on the gauge, run the proper size wire for what the circuit will be fused at. You don't want to run something like an 18 gauge wire and then fuse that wire at 20A.

Use heat shrink tube, not tape.

Re: Wiring Novice Question

In this case I don't think you'll need to worry about the 4 amp dash light fuse being too big for the wire but that is something to always think about.
