Where to take power for my koso water gauge and AFR gauge ?

Where do you take the 12volt switched power for the gauges ? I would like them to power up when the dash does. Also where do the boost gauge sensor hose go on mpi 180 kits I don't see a nipple anywhere. Thanks for any help guys

Brown wire(I think its brown) from ignition provides a fused 12V source. Pull back grey outer cover and tap into it. Its easiest to remove key switch from dash and splice into wire with it out.

I'm guessing that should be fine to power up my koso LCD gauge and my AeM wide band as these should only draw minimal amperage

I run a ZEX switch and a GPS off of it and never had a problem for 3 years. I believe that is a 20 amp fuse. I always carry extra fuses anyhow. I wouldn't add a larger fuse to compensate.
