4 pin relays for headlights

I plan on using weather pak type sockets and on going with a gel battery or lithium ion type if i have the coin when i am ready for it. The relays and fuses will be mounted inside a weather resistant project box that will be bolted upside down to the battery tray. They will be mounted to the inside of the lid which will be hinged at one end, and have 1/4 turn fasteners to open it to access the relays and fuses. The buss bar will be inside the box as well. The only thing that will be exposed will be the wiring going in and out of the box. Everything will be neatly hidden from view.

Mr Crackedback PMed me the tyco and bosch relay PNs. I checked evilbay and found these PN genuine bosch and tyco relays for about $7 to $11 each. Pretty inexpensive IMHO
