Re: european headlights install (corradoian)
not hard
you can run them with or without relays
I been running mine without relays for 2 years now, no problems just not as bright as cars with the relays installed, but still briter than US-spec lights
if you get the actual plug that plugs into the back of them than you just clip off the stock plug for the headlight and signal wire from the parking light and spice them together, pretty straight forward. thats with out the relays
with the relays you have to create a wiring harness to supply direct power from the batary to the relay, ground all of the relays and such. still not to bad though.
I currently in the process of building a wiring harness for the euro lights using 4 relays and wiring up the automatic headlight adjusters.
I using all stinger wire and stereo style blocks, getting deep and very expensive. My lights should be really bright then.
