I beleive the headlights should be a direct fit replacemet correct?

I've also got thje leveling switch coming etc, however, no wiring harness. I did a little searching and found an article on scoobymods.com that appeared to describe the same thing, only for bugeyed wrxs.

Anyone know what woudl be involved if I want to hook up leveling switch? Can I run headlights without them (will they just take default setting, say 0 or whatever?)

Thanks in advance for anyone who's ventured down this road.
