Wiring Hi/Lo Beam

[farmerj]

OK, showing ignorance here but need someone to confirm what is probably obvious.

I added a 6" light bar to my XC a while back, with harness and relay. Now I am upgrading to the LED and want to add in the Low Beam.

I purchased a new SPDT switch (two position) to replace the single-throw that I was using to run the light bar, thinking that I would just run a wire from the switch to the low beam.

But that's not how it works, right? Do I have to run a second harness and relay back to the battery for the Low Beam (as well as the high beam)? Or is there a way to simplify?

Thanks,

Jeff
