The solid (thicker) grey cable in Pin slot # 1 is the dome lamp circuit. The thinner grey wire with a light green stripe is the Puddle lamp. The Puddle lamp is Pin Slot # 8. Counting from right to

I plan on tapping the puddle light when I do my step lights. It makes the most sense. They will only come on when needed and no other system will turn them on.

@Crazyjoker77 light strips are mounted to the lower rocker panels as close to the running board mounts as I could get them. They use the same 3M tape as vent shades and hood protectors have. No diod m

I ment to update this. I forgot I had turned the locator function on. So after turning it off, no lights come on till I open the door. Then it's only the dome, puddle, and my running board lights. 

So, any door that's opened activates the step lights?  I think this is the way I'm wanting mine to ultimately operate when I get them installed.

 That is correct. As long as it is dark enough to trigger the light sensor

Help with the puddle lights. What am I doing wrong? I connected my LED positive lead to the grey with green trace wire in the X7 Grey connector on the BCM. I connected the negative to a bolt that goes is screwed into the firewall. They will not turn on in the dark, even when I  cover the light sensor on the dashboard with a coat. Not when I unlock the truck or open the door   The truck is a 2015 Sierra. I must be doing something wrong. The connector that the puddle wire uses doesn't have a ground connection according to a PIN out diagram I found.

I would connect it to the dome light in the BCM just to make sure it’s not a wiring issue on the LED side. Then you can start wondering about the truck itself. Does your truck have the puddle lights in the mirrors? If not, I’m unaware if that connection would get power at all. PGamboa would know. I just don’t.

I used the same grey with green stripe wire. For ground I used one underneath on the frame. It is pretty much inline with the parking brake grommet. 

 

Are you sure your lights worked in the first place?

I tested the LED's they are fine. Someone said to check that My locator lights are turned on in settings.  They are.  used an ohm meter to check that the wires were fine. My truck is a 2015 GMC SLE. Maybe I need to test the voltage coming from that connector into that grey and green wire. I guess I can connect my DMM to the position on the plug, cover the light sensor and watch for the voltage.

Yes. Check voltage on that wire. All 2014 trucks and some 2015 will not output voltage or might only output 3vdc. In this case, there I have those trucks perform a diode mod and grab power from
The dome lamps.

Nope. These are not stock puddle lights. I am adding them, or at least trying to.  :)

That may be the issue. They my not be enabled in the BCM. @pgamboa on that.

Thanks for the hint on the low voltage. I will check that. Regarding the dome light diode mod - 2 questions. 

I already added additional LED's for foot well lights.   How much current can that circuit handle?  Last question - if I use the diode connected to the dome light circuit, do I just connect my new LED wire to the negative side of the diode, ( stripe on the diode) since the dome circuit would output 12V+ I assume at that connection.  Or do I bridge the diode between the dome connection and the puddle connection on the grey connector, then slide my LED wire in next to the diode wire that is now bridged between Pins 1 and 8 at PIN 8?   THANK YOU !

Do you have the bed lights? That's what I tied mine into, they come on with the cargo light. I can take a pic of each side when I get a chance today

Can you take a picture of how the lights are tied into the bed lights please.

I'll try and grab a pic, the wires are up tucked away in wire loom currently

      2001 GMC Sierra - Banging feeling in steering wheel

      By txab · Posted

      Without knowing how bad your banging is, one suggestion is the intermediate steering shaft on the steering wheel. These used to be a problem on 800 and earlier series. The feeling/sound was sometimes described as "clunking" and was felt in the wheel. Also there is a plastic piece in the lower column that is referred to as a bearing. Not your traditional looking bearing though. Your ball joints, bushings and tie rods or steering rack (if equipped) are the main point of issues. You never mention total unit miles, only that you've put 60k on it.   You can search the site for help on the ISS description. Plenty of these have been replaced   https://duckduckgo.com/?t=ffab&q=site%3Agm-trucks.com+intermediate+steering+shaft&ia=web

      Yes I have is set with the 1mm disk (Minumim Tension), for spring spacing and I raised my truck in the rear 1.5". You can go 2mm  and I think 3mm if you need.Minimum. We are on our way to TN from GA.. My wife is driving and stated she cannot believe  and   stated she can not belive the difference.

      Most 1 ton trucks come with the factory overload spring, which need to be removed for installation of RoadActive Suspension. Removing the overload allows proper fitment and ensures the system works as intended. The RAS® Mega-Duty kit will reduce squat and provide significant improvement vs the factory overload spring.

      I wonder as well, why they would send me a text message with links to these suggested procedures totalling over $10,000 without even the slightest hint of how they arrived at these being necessary.

      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.
