First, thanks to all who have answered kindly my sometimes amateur questions about wiring. But, alas, I have another:
From the 9004 male adapter, I would run three wires from each: one to the high beam relay, one to the low beam relay, and yet one more for a ground (although Ryan R said I could just attach nothing to that pin out). This would, in turn, be used to activate the relay. I get this. Now, for my question. There is only one input connection on each relay (86 on the Bosch). How, then, can I attach a wire from each 9004 adapter to activate, for instance, the low beams when there's only one input? Or, does this tell me that it only requires one wire per relay to control the relay?
Thanks again.
