I recently bought h.i.d lights for my 14 silverado and I got the wiring harness that hooks to the battery. My question is my harness is only a single input so it only uses one of the factory headlight signal. So would I need to get a dual input harness that uses both factory harness plugs or will everything be ok with just using one side.

Oh and when I say factory signal I mean the plug that plugs into the headlight bulb. The battery harness I got for the h.i.ds only uses one

 

It only needs one, that's just the signal wire to turn them on and off.

 

Alright sweet thanks for clearing that up for me.
