Thanks guys.
Another quick one - I am installing a/m gauges (temp and oil pressure) ... if I just jack from a current fuse at say 20 amps - and the gauges are 5 amps ... I can just put an inline 5 amp fuse between the fuse box and gauge .. right? The amperage is really what is being "pulled" from the source not pushed? So where I clip into a 20 amp fuse - what is already there is pulling/loading plus the gauges .... the 5 amp fuse between that and gauges just protects gauges? And the 20 amp fuse is protecting everything on that circuit from pulling over 20 amp all together?
Or am I all messed up in the head?
