Anyone happen to have a wire diagram for the headlights on 07+ NNBS Silverado? I'm trying to work out what the different colored wires are for so I can finish making my wire harness for my HIDs. The wire going to ht e lights have a yellow and black but the plug from the HIDs has the yellow wire in the factory harness going to black on the HIDs and the factory black wire going to red, is that right or did they put the plugs together wrong on the HIDs? I had everything hooked up correctly but one of the lights had a slight flicker to it.

 

 

EDIT: I might have posted this in the wrong section, would I have better luck posting in the How-To section?

Well, I went out and got a multimeter since mine went missing when I moved. Looks like the yellow is + and black is - like it should be but the connectors that came with the HIDs are not right, just had to pop the pins out and switch them. I also finished making my wire harness and no more flicker now, I'll have to wait till its dark to give it a good test.

I think all HID harnesses are wrong. I have read so many people that had them wrong. Most of their connectors they just flipped over. Can't be a very good fit if they can just flip the entire connector and it goes in.

Those don't blow up very good....the originals are a lot clearer in Adobe. I don't know how to post them any other way.

Mine don't just flip over, they are keyed. I had to release the pins and relocate them. I ordered a cheap harness which is why they probably worked but the fact it was cheap could have been the cause of the flicker. I ended up taking the harness apart and just using the relay and connectors so it was plug and play. I used heavier wire, crimped and soldered the connections and used liquid tape and heat wrap to make everything nice and clean.

      OCI, not when but why?

      By Grumpy Bear · Posted

      https://precisionlubrication.com/articles/oil-filter-efficiency/     For them it is a problem of $$$$ and compliance. To cover both they have to lie from the heart.    Government wants low waste oil numbers so the bar needs to be very low on contamination to met that requirement.  Consumer wants cheap maintenance (perceived cost). Again requiring a low bar.  OEM wants high margins at a cost effective warranty rate and lots of repeat customers. More low bar.  Filter manufacture wants the same thing the OEM wants. See the pattern?   Consumers are fickle and also want perfection requiring a HIGH bar. Inconsistent with all of the above. Consumers can be, when the put their minds to it, inquisitive, love winning arguments which requires some useful information to be available to support them. And this is where it gets sticky and the lies begin.    Information needs a solid well grounded point of reference if we are to compare in a useful way. There is a standard for this.  ISO 4548-12. This standard sets the particle size at a specific Beta ratio and darn few are faithful to its intent.    If they don't state the test method they change the particle size or the Beta ratio to hit a perceived favorable standard. They obscure the information in a way as to prevent direct comparisons leaving the consumer with one method. UOA's with an ISO 4406 test result. Pricey and not allot of labs willing to do the work. Lobby work happens everywhere, not just at the seat of government.

      IF,IF,IF. If they cared about quality instead of profit and this applies to any company, what a concept.

      2001 GMC Sierra - Banging feeling in steering wheel

      By Christopher Miller · Posted

      Good Morning Gents..hope everyone is enjoying a beautiful saturday morning. I have a 2001 GMC Sierra that I bought used in 2018. I am the 2nd owner and its a beautiful truck. Ive put about 60,000 miles on it and recently the front end has felt funny. Kind of loose when hitting bumps adn sometimes I actually feel a "bang" in the steering wheel. I took it to a local guy who said that everything was tight and he tightened the steering box. It didnt feel much better, so I had him replace the front shocks, which had noto been done since I bought it. It had the check enging light on so I took it into a local garage to fix that and check out the suspension. Everything is original and the rubber bushings that I can see look bad. They said everything was tight and there wasnt any play in the front end. Im concerned about the banging feeling in the wheel. Ive been driving this truck for 8 years, so I know how it usually feels and this is something new. Its a second vehicle, so I dont drive it all the time, but Im trying to use it more often. I live out in the country and some of the  roads are kind of rough and I alive on gravel roads. Anyone deal with anything like this before?

      Well, 2 no-bid contracts to donors didn't seem to result in a good job...
