^ thank you-
And i applaud that you are thinking ahead- 12 ga between the fuse and relay would be fine. the 16 ga from the relay panel to the switches would be fine. But i would use 8 gauge going from the relay panel to your 50" light bar as long as the total length is under 15 feet for 20-25 Amp applications.
That probably makes sense, I'll need one different terminal for the 8AWG output to the accessory on that relay though I suppose, correct?
Also - I plan to tap behind the window switches for acc power to light and power the switches. Should that be able to support 4 switches no problem? I am concerned about someone flipping a switch with doors off and running down the battery.
