Can anyone reccomend a good power source to tap my gauges to that does not cut during cranking? Is it a good idea to use the IGP1 yellow/black and put additional load on that circuit? Potential 2-3A total load.

I believe there's a fused Connection on the fuse box you can utilize... I don't remember which is the one, or if it cuts while cranking. Best bet is to tap just off the ignition switch harness; unplug the s terminal from the starter to expirament with which wire it is.

Maybe a small 12V rechargeable battery to power the gauge with a diode between the cars battery. That way the gauge keeps its power while starting. The diode will prevent the small battery to fall below 12V.
