What's invloved in swaping a GMC tail for a chevy on an NBS specifically an 05 Sierra EXT. I know the tails are the same size and the mounting screws are all in the same place but since the light design is different what needs to be done to the existing GMC wiring harness to make it work with the chevy tails?

Do you mean for example say Tailights from an 03 Silverado to your 05 Sierra?

 

For simplicity sake let's compare 05 to 05. I believe 04 to 04 classic where all the same for their respective brands, something tells me there was something different about the 03's and parts catalogs seem to agree, I'm just not sure what it was since there appear to all look alike. Looking at it another way if an 03 can make use of my existing wiring harness that would be good information to know assuming to light pocket and mounting holes all line up.

The different's is that the 04' and up Taillights have a Black border around the fame and the 03' does not.And 03' & up,have 1 Extra Bulb at the bottom of the Taillight.With that there are 2 ways to fix that.the 1st is to do a hard wire for that bulb or pickup a set of 03' & up Harness.

 

Here is a link for the hard wire,

Thanks for the link 99Heartbeat, looks like an easy enough swap and if I can score a harness at the right price I'll have hit gold. I may actually have most of the parts to build my own anyways as I have a couple tail harnesses from a Cavalier and something else around the yard.

 

Off to the bone yard one of these days for a scavenger hunt. Price of scrap is still down so most yards have a fair selection of vehicles but tails are usually not something they let go real cheap.

      Lower trims ( WT, Custom, Silverado ( aka LT )

      By actively-shopping · Posted

      We've been fans of the 40-20-40 front seat in the lower trims; specifically the leather option on the "3-across" version of the  40-20-40. I hope this can still be ordered in the "Silverado" or RST trim packages.  AND .... if dual exhausts are a part of the Custom trim,  does that mean a V8 package is available on Customs ?  Has the RST trim been discontinued ?  When ordering a V8 on one of these lower trims .... must it be the 5.7 ?  Or, on 4WD units can the 6.6 be ordered ?

      I like it.   In a world of vehicle front ends that look like they've had a little too much nipping and tucking, I appreciate that GM went with a bold and professional look for the new Silverado and kept the aggression understated. The new 1500 looks a little more like the current 2500.   The interior looks well done as usual, although I'm not a fan of billboard screens on the dash. At least recess the gauge cluster screen. I see passenger screens as "keeping up with the Joneses'" in automotive interiors of late, which is fine. I don't think they belong in most pickups, but choice is good. Maybe some day I'll appreciate having one. Probably not, but, maybe.   Yet another steering wheel and airbag design. I wonder what it costs to have so many different models of airbags and buttons and steering wheel frames. IMO, pick a good one and stick with it. The new one is very...luxurious...looking. Again, not bad, but also not what I'd expect in a pickup.   GM has left us awaiting engine choice announcements and official details.     What will I be ordering on day one?   Nothing. I like my 2025 and it would be silly to get rid of it just to have a 2027.

      I'm also waiting to see if they confirm Apple CarPlay, because I'm not interested in subscription fees just to use the hardware I already purchased.    In closeups it looks like it gets the Colorado/Canyon center screen based headlight controls which I despise. They also appear to lose all the hard switches for functions like seat heating and cooling, parking sensors, lane control, traction control, etc. which means they're all screen/menu based, so verdict is out on how well those will work with gloves or wet/dirty hands.  Admittedly they don't show the left knee area of the dash, but I don't see hard switches for locker control on the ZR2, and the "mode" switch appears to eliminate the rotary dial with a quick way to access tow/haul.  My 2021 has had multiple screen failures and at times the screen just locks up, goes black, or reboots while driving even after replacement, so loosing the ability to access many of these functions, especially lighting control would be pretty frustrating.   There aren't enough photos or detailed trim details other than one mention of "available microfiber trim" to confirm, but the use of microfiber on the seats and or center console is a deal killer for me.  Just because you drive a ZR2 or High Country, doesn't mean you don't work out of it, and that material is difficult at best to keep clean and looking decent.   Lexus and several other brands are using it on seats, dash, and door panels now, I assume as a cost and weight saving measure,  and it looks horrible 1-2 years into ownership.  I see what appears to be piano black on the doors and center console in some photos, which also has no place in ANY vehicle in my opinion because it mars and scratches too easily, especially for a truck.  Will be interesting to see what GMC comes out with when the Sierra is released as far as materials go.

      Im a fan.  Simply moving the screen up helps the look of the interior.  I feel like GM dropped the ball on the current gen having the screen not at the same level as the top of the gauge cluster.  The GMCs look better with the vents above the screen to close that gap.

      OCI, not when but why?

      I hear you, its just not something one would even think of that the new oil in the container isn't filtered to a spec one would expect it to be.    As to a passenger vehicle theme and the maintenance requirement to meet to ensure a warranty is honored, these days with claims of life time transmission fluid on some models and the limited amount of oil changes that would bring one to the end of the factory warranty, that sells vehicles for those that like to hear "easy care maintenance free", but the manufacturer certainly knows different as to what that more than likely means for the longevity of some of the components if given that minimum spec maintenance. Then again I imagine there are a fair number of people that really don't care as long the vehicle gets them a certain number of years down the road because they are the type that want the next new thing, new and improved ... more bells and crap etc on the new one on the show room floor. Manufacturers have learned the phycological game to entice the customer out of their money !
