My 2000 Gmc sierra 1500 that had a complete frame up rebuild using a 2005 complete rolling chassis as well a low mileage 05 5.3 vortec and the 2005 main wiring harness front to back .problem is the push button 4x4 doesn’t light up but if i pull the 4x4 fuse in the cab and i just barely put the fuse back and wiggle it up and down i get some clicking noise and for a second the push button flickers . is this a bad ground or punched wire causing my problem before i ripped the truck apart because of a rotted frame for the rebuild the 4x4 worked but the 2000 wiring harness was completely full of water and had to be changed . By the way the front drive shaft is removed as well as encoder motor because it was stuck in 4x4

it sounds like you have many issues ongoing.  Making sure all of your grounds are hooked, is the first thing.  I am not sure of the compatibility of your bcm and ecm with a 2000, vs 2005.  It may be a matter of just taking it to your local gm dealership and getting things reprogrammed.  I am not sure what frame up means, but if that means you got a frame, and a cab........... from a 2005, then what exactly did you take from the 2000?

Frame up means everything on the frame was restored to like new condition . story is i bought a 2000 gmc looked mint then discovered the frame was bad behind fuel tank. 

 

My friend who sells gm trucks found a very low mileage 2005 truck that it’s older owner had rolled his tuck into a ditch but everything else was in like new condition. We took my 2000 cab and box and put it on the 2005 frame . used the 2005 wiring harness because mine was full of water and put in a good used computer and it was reflashed 

 

 

push button switch when i first bought  the truck from the dealer ,  each 4x4 selection button did  light up and worked  now nothing unless i wiggle the fuse it flickers for a second

      Thanks!  I figured as such; GM and other manufacturers have used standard parts and harnesses across trim levels and such for decades.  I pulled the blank accessory cover off of my commuter van (a 2016 or so Chevy 15-passenger) years ago and found the plug for a USB outlet.  It wasn't connected to anything, though (I tried swapping in an outlet from another van).  I was a GM Tech years ago (late-90s) and was pretty familiar with my 2006.  I might be wrong, but I view newer vehicles (pretty much anything made in the past 20 years) as being a lot more plug and play.  Meaning, more unused wires and plugs unless you have the Mack Daddy of vehicles.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.
