Clifford NightVision

Has anyone fitted this unit ? I have just received mine from a dealer in the US (cant buy this stuff in UK) and the install manual has the full wiring diagram.....except for the white wire. On the diagram it says "Headlight Input - See Text" and there is no text. This is not the wire that powers the headlights (red black) or the sidelights (brown).... Help...im stuck....could try wiring it without plugging this one in to see what happens but not confortable with this approach....

i have never heard of that before, what exactly is it...

I just looked up the manual, says the same thing. I don't think it's used....I will check the manual for the one I have at work tomorrowShaughn Murley

xaudiopipex - Its the auto headlight activation module. When it gets dark, lights come on.... Extreme1 - thanks, that would be very useful.

If you are talking about the stand alone nightvision the wire you are referring to should be white, and is not needed in most cases.  it is the 87a input on the headlight relay, with the thick red or RED / white being 87 and the RED / black as terminal 30.  You use this wire if you cut and interupt the headlight wire of the vehicle.  this will prevent backfeeding in to the ignition circuit if the headlights only come on while the ignition is on in the vehicle.  such as volkswagens

scirocco hit it on the head, on vehicles suchs as VW, Audi, Focus etc it's to isolate the headlight switchShaughn Murley

Thanks for your help guys.

Thanks for your help guys. Is BMW included on the list of cars where this needs done....I have a 99 BMW 3 series. The lights on the BMW do come on when the ignition is not on, the feed to the light switch is perm 12v....

Guys, as you know, this module drives only a headlight. I wanted it to switch on dashlighting, headlamps/sidelights and rear lights. Instead of using diodes, I used the following relay assembly to isolate the supply wires when the vehicles switch is used.... So basically, the switch always takes precedence over the nightvision module. Just in case I want the lights on but its not dark enough initially for nightvision then it gets darker. I dont want 2 feeds into the lights.... Does this configuration pose any issues....? It seems to work in practice. Any easier way to do it (without using diodes - not a big fan of these....)
