Hey all, new to the site and I am wondering how I can properly add in some small led light strips to the underside of my power tow mirrors that will come on when I unlock the doors, like when the perimeter lights come on.

The truck is a 2004 GMC Sierra SLT 1500...

And where is this rap relay located, I've looked in the under hood fuse/ relay box and can't find it. But I have figured out that there is a puddle lamp relay in the body control unit/module, which I don't know where it would be located in the truck. My truck is an SLT with front bucket seats and center console....if I can locate that, then I can plug into that since my truck did not come stock with the mirror mounted puddle lamps.

It would be internal to the BCM. The BCM is located right above your knees when your sitting down in the drivers seat. It is behind the knee bolster.

 

After looking into this a little more. Your best bet is to wire a relay into the system off the IP Fuse block.

I found that gm in the early 2000's started using what I would call universal wire harnesses so that the same vehicle can have different options but all used the same harness, I found that out with my 2004 Colorado that was two wheel drive but the center dash where the T/C plugs into it was a wire plug of like 15 wires...TC doesn't need more the two wires...so I hope this truck might be the same wiring wise....

iirc don't your dome lights come on with the perimeter lighting? or do you cancel them out with the switch on the dash? you could wire in with the dome lights to activate your after market puddle lights. the dome light wire should be gray/black.

Wouldn't be hard. Tie into the Rap relay is how I would do it. I just put a set of these on my truck for fun and they look great. lol http://amzn.to/2jsJTe2

I saw 2 reviews, are both of yours still working, Chris?

They are but I have only had them on about a month. I did make one minor modification. The clamp on the circuit board isn't sealed at all. So I siliconed it shut so the rain couldn't get to them. I am pleasantly surprised at how bright they are as well. I actually have them under the bumper of my truck so when I push the brake light they come on. I think I am going to change it so it's on only when the park lights are on. Lol

I actually have these since my truck is a Chevrolet. http://amzn.to/2BjiWFe

Gotcha, I was thinking about getting the gmc ones but saw the reviews and was worried. I think I will hook mine to the reverse lights, that way they will come on when I hit the unlock button and then only in reverse.

I bet they are getting bad reviews because the circuits are shorting to water. I mean the circuit boards are cheaply covered. But if you prevent water from getting to it I bet they will last a long time. I will post a picture of what I am talking about. I bought an extra set for my daughters car. I am gonna put her's in the door so I will not be sealing hers due to their won't be water as high as I am going to wire it.

      No 12v outlets in 2026 gmc Sierra

      By PhilB · Posted

      It is possible to add your own 12v outlet to your truck.  Check out this video:   I verified via GM Upfitters that pin 31 is the same on the 1500 trucks.  The wire is GM part number 84779405.   You can get the GM 12v outlet from Amazon  https://www.amazon.com/Genuine-Accessory-Receptacle-25774623-13549530/dp/B0F1H9YRGF EWAY 12 Volt Power Adapter for GM   https://www.amazon.com/EWAY-Chevrolet-Silverado-Cigarette-Ignition/dp/B0915RRW6Q/ref=sr_1_1?   I just haven't figured out a good place to put the 12v outlet in my truck.   Some people are getting USB-C to 12V adapters  https://www.amazon.com/WYMECT-Cigarette-Lighter-Socket-Adapter/dp/B0F87WNQKB/ref=sr_1_1_sspa? Not sure if they provide the correct amperage that a device like a tire inflator would need.

      Wiring Help, Please

      By Core-Lokt · Posted

      Thanks; I looked there a few minutes, and I think I can find something. I really never looked there, as I thought it was stuff like PTO/aftermarket bodies/accessories like snow plows.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Different requirements for oil filters?

      By Grumpy Bear · Posted

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
