Hello all, purchased a set of 6v Halogen Headlamps with the 6v H4 bulb that is 55W/60W low/high from Dyck a while ago. I am wondering how to hook them up?

I have ordererd two 6v relays. I'm assuming I will need a separate higher Wattage fuse installed somewhere to handle the higher draw.

I had heard of using an unused slot in the fuse box, but all of mine are filled, so I was thinking I would need to use the inline type.

Then need to figure out how the wiring needs to run including where the relays should go. Would like to keep as close to original as is practical/advisable.

Any help would be appreciated, electrical is not my strong suit! Thanks
