Euro lights install

[motogo1]

I'm starting a Euro headlight transplant on my 91 200. I've got info from
the net about building a wiring harness with relays for these babies, but
being a 'basic knowledge' kind of guy with regards to things electrical, I
thought I'd ask if anybody that has done one of these projects would share
some info. Any info on what kind of relays, inline fuses, connectors, etc
with specifics and sources and tips on the install would be greatly
appreciated. TIA
