Default Might want to ...>>

Trigger that fan with a relay. I forget what they draw, but I decided, since I was utilizing some existing power in the rear center console, to do some low amperage switching there and avoid any potntial issues..I figured, since Spal sold a relay kit, there probably was a reason, and I originally had 2 fans on that circuit...

Default i'm sorry i must be stupid but....

don't the led's only get power once the headlights come on? so won't the gauge only work when the headlights are on?

Yes, which is why you only want to connect the white wire to what I posted last night.
