It may seem silly to you, it's just that I probably cannot picture it in my head, but why do I need a relay if I can bridge the positive from H1 to the H4 high?
I'm stuck in this area.
In my mind, if the high beams are on then the H1 with feed the H4 high positive. Am I jumping a few steps here?
When the low beam is in use the H4 high (filament) should not have any power. I believe the Innovative harness does not provide any power to the H4 high. So if nothing "feeds" it it won't turn on. But when the high beam is on, the H1 would be able to supply power to H4 high via a separate wire.
The only issue I see here is that I will over load the H1 wire from the car's harness, since it will feed two bulbs (per side). Probably melt too if the high beam is on for a sustained period of time.
Is this where the relay comes in? To keep the load even?
