@thewabbit1 If you could draw this up for me, I only use 1 relay when I wire up my driving lights on my subaru's. Hopefully I can explain it.
So the switched side of the relay remains the same, + batt to relay, relay to Lightbar/driving lights ( make sure it is fused )
the switching side goes like this, from a switched +feed ( i use the cigarette lighter) to your cabin light bar switch, from this to the relay, then from the - side of the relay to the switched negative on the Highbeams.
I hope that makes sense ( i dont usually even run a cabin switch,I dont usually see any reason to have the Lightbar/Driving lights switched off which simplifies the wiring even more as i take the switched side for the relay straight from the headlight, one+ and the switched - )
