Need an answer real quick,boost gauge wire size.

I was using 12 gauge but it seems extremely large for what I am doing (wiring to the dimmer switch) should I just go ahead and use it? or use smaller wire? the dimmer switch wires are about 1/5th the size of the 12 AWG

Should use 16 or 18 gauge. It will match up better to the dimmer wires and be easier to solder.

I think the autometer gauge says to 18, but don't quote me on that.

16 gauge.

16 to 18awg is what to use. 12awg is way too large and not needed

yea I ended up using 16g, I had already wired the 12g to the back of the gauge and mounted it so I wasn't about to refish wire and reconnect that since it was getting dark and I needed the car for work the next morning.

I installed spade connectors and soldered the 16g to the dimmer left about 4 inches and put a female spade connector on it, then put the male connector on the 12g and plugged them in.

Going to leave it like this for now until I install my AEM UEGO gauge where I will replace it all with 16g.
