I'm sure I'm overlooking something obvious, but I haven't been able to figure it out, so I'm hoping somebody who's been into the headlights can set me straight. I'm doing a simple fixed headlight conversion very similar to the style Eric Krause and Pablo Crespo did on their cars - replacement of everything with a pair of Hella bi-halogens, crafting buckets out of aluminum flashing to fill the hole in fender, and covering the hole with a piece of lexan (which I'm planning to curve to match the contour of the fender).



Anyway, the wiring looks extremely simple, as there are just two wire bundles, one of which (the one on the left, the smaller of the two with three prongs in the picture) goes into the light bulb, and the other one goes to the motor drive mechanism. When I turn on the headlight switch, I don't get any voltage across any combination of the three leads of the headlight connector, nor do I get anything across any combination of any of the five prongs in the other connector. And just as a sanity check, the stock light bulb doesn't turn on when I plug its connector into the three-prong connector shown in the picture. All the other lights on the car seem to work.



So, what am I doing wrong? The Hella light has two two-prong connectors, one at its very back which going into the bulb, and another one which is the switch for the high beams. So I need to connect these connectors to the appropriate ones from the car. Thanks.

Bump. I know there tends to be a lot of traffic on Mondays, so I don't want my query to be buried too deep, in case somebody with knowledge about the headlight wiring has there View New Posts time horizon set to 24 hours.

The........key.........? Curse Al Gore! In the good old days before the internet, you could say or do something that proves you're a complete idiot, and unless you were doing it on a stage in front of a large crowd, only the few people in your immediate vicinity would know about it. In addition to yourself, of course. But, no! Now that we have this internet thingy, it only takes a few strokes on your keyboard to demonstrate your stupidity in front of potentially millions of people (OK, not on any 968-dedicated sites that I know of...). Just because none of the other cars in the family need the key to be turned to activate the lights, I'm stunned that it never occurred to me to try putting the dang key in the ignition. This calls for what Click & Clack refer to as a Nuclear Dope Slap. At least I was right about thinking I was overlooking something obvious <img src="/forum/images/smilies/968/mad.gif" class="smilie" alt="" /> .



So, of course, once I put the key in the ignition and turned on the headlight switch, things came to life, and the voltage readings with the lights set to low beams and high beams make sense. OK, now I can wire up the lights to do a cursory test of their aim (the car is on jack stands, and is pointed to a wall with a ton of junk in front of it, including my work bench, that I don't feel like moving, so it will be a very rough test), and then install the buckets that I've built.
