There seems to be a a little confused info about wiring. I dont know about vento lights, but I kinow for starters you need the correct headlamp switch with adjusters on it. There is an extra connector needed to go into this. As for the motors, you will need a light loom with them on(I think) similar to your usual loom that has the large multiplug above the radiator. You will not need a new dash loom if you have a gti or similar as the wiring already exists.
