Crimp vs. Solder & wire coloring?

[David]

Well, I'm finally making the jump to E-code headlights. I have in myy possession a set of Euro 80 headlights (H4s). I'm assuming the physical install is pretty easy, but if anybody has or knows where I can get detailed step-by-step instuctions, I'd love to have them. Anyway, I'd like to get the lists thoughts on crimp versus solder. Obviously I need to cut the current headlight plugs off and install H4 plugs. So, what's the best way to attach them? Crimp on connectors (butt connectors?) or solder the wires? Coming from a marine environment, I say crimp. Crimping is the standard on all marine wiring jobs as they have to withstand constant vibration and exposure to the elements and solder joints tend to break. Thoughts?  Then, Anybody know offfhand what the wiring colors are for the headlights? I mean the color of the wire for +low, +high & ground. I want to get these lights in ASAP. I know Santa will be bringing me a proper relayed harness from SUVLights, but I'd really like to run them for a week or two without relays. That way I can see what the difference is betwen DOT & E-code then how much a differnce relaying makes...

TIA!
