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

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
