Porsche 944 - Headlight Wiring Harness Repair Tutorial 

Thanks! Refreshing the yellow zinc plating on all the steel parts makes a huge difference. That, and adding in all new fluid reservoirs… and cleaning, cleaning, cleaning. I’ve probably taken it too far at this point. 😂

I learned the hi & low beam switching was my own dumb oversight, but now that it's working I noticed the driver's side high beam isn't working. Thanks to your video I checked the wire instead of just buying a new bulb--it's the wire!

That’s awesome! Sounds like a great car you’ve found there! I’m glad the channel content has been so helpful. 👍🏼

Nice! I’m glad it helped. 😁

Thanks, it’s still holding up well so far… Although I’m not quite sure how many more actuations of the headlights it bought me before the wiring fails at another point in the harness. 😂

@@NC944er If it fails again you’ll know how to repair it. Or, you can get all new wiring and install that.

Thanks David, that’s very generous of you, I appreciate it! I’ll let you know how this repair holds up for a bit. 👍🏼

Nice! Yeah, I bet the LEDs make a big difference. Since the deer incident, I don’t have the 944 out on the roads much after dusk, with the freaking things always jumping out of nowhere we live. But, the LEDs are another route to consider for sure. Thanks for sharing. 👍

Yeah man, the side markers take on a lot of water and the o-rings fail to keep moisture out. Mine on the driver’s side where lighting intermittently after replacing the bulbs. It turned out to be oxidation inside the metal cups that hold the bulbs in place. After cleaning those contacts out with a wire brush and some sand paper, there were illuminating again.

Hey man! A ‘no start’ condition could be caused by any number of items, but based upon the systems you described leading up to the failure, it’s sounds like a fuel supply issue or lack of spark, but stalling/hesitation on acceleration could also be a faulty AFM or a vacuum leak. If it were me, I would test the sensors - AFM, speed, reference - bypass the fuel pump DME relay to rule that out - and then attack the fuel and ignition systems. Even though the pump is running, a clogged fuel strainer, fuel filter, or injectors could inhibit fuel delivery to the combustion chambers. If you’ve got adequate pressure at the fuel rail and the injectors are firing, it’s easy to check/replace the spark plugs, ignition rotor, and distributor cap. The ignition circuit on the DME computer can fail as well, not sure if you have a spare DME to swap in and test, but that list is something to work through.

😂 You’re also the top channel commenter at 106 and 30 hearts received… so it’s officially decided, you need to pick up another 944.

@@NC944er you would be extremely happy with the headlights that I upgraded to, the morimoto retrobright in one of my videos. Much brighter, better pattern, less power draw and wide voltage input range.

@@NC944er I miss my car, it was really a special one and really a good car. But, I have a 4wd project going strong right now so I don’t see another Porsche in my future at this time.

@@tims_4x4_garage Ok, ok, fine… we can compromise… a 944 Safari Build! 🤣 Best of luck with your 4x4, I’m sure it will turn out great with you at the helm.
