What Happens If You Turbo a 5.3L Yukon With No Other Mods? PART 2: Fuel Injector Upgrade! (RIP 4L60)

What happens here

Due to different connector types on the new injectors, the existing wiring harnesses need to be modified. The team decides to use butt connectors with heat shrink. Each wire on the old connector is cut, the ends are stripped, and then crimped into the appropriate butt connector along with the corresponding wire from the new injector pigtail. A heat gun is used to shrink the heat shrink tubing over the butt connectors for insulation and weather sealing. This process is repeated for all eight injectors.

Goal: Connect new injector pigtails to the vehicle's wiring harness.

Tools and materials

  • Heat Gun WAGNER — Shrinking heat shrink tubing
  • Heat Shrink Butt Connectors — Splicing wires and providing a sealed connection
  • New Injector Pigtails — Connecting the new injectors to the vehicle's wiring harness
  • Wire Cutters — Cutting wires
  • Wire Strippers — Stripping insulation from wires

cool then we'll have to cut these and change them to these fun stuff you're gonna do that right all the important electrical stuff that's your job yeah if you want it wired like my bedroom that's a different story what what happened with that tell the people um i took it upon myself to be helpful and rewire all this in my room you were trying to change the light switch to a different style weren't you yeah i did that and i changed like like the wall plug-ins and all that like i turned off the power to like the whole house and everything so i wasn't stupid about it but i definitely did not know what i was doing it still works but like the closet light may or may not control the fan and like everything else so your fan was running for like six months wasn't it yeah until i told my dad what i did torture test on that fan yeah so you turn the closet light on and your fan turns on yeah and my night lights this did work by the way it did yes freaking sweet so that's all bolted down now uh now i can get to changing the pigtails over nice now we are changing the pigtails over can you hand me one of them the new ones these came with the injectors this is what we're using using some heat shrink butt connectors tanner said don't use solder because it creates resistance is that what you said yes so um take the word of super tuner tanner don't use solder i don't know these connectors just seem weird to me if i'm going to use them i like to use the heat shrink ones or the raw ones and then put black heat shrink over them because they just are not as bulky i just think the bulky non-heat trick ones like look really bad like the ones i use in the iat sensor a few videos back you should go uh check out the other videos on this thing there's a whole playlist for this entire build if you're new to this you can see the whole thing from start to finish down to the day i picked it up from my uncle with stories from my uncle and my grandma so check it out it's uh every build on my channel has its own playlist if you didn't know so you can binge stuff really easily what did you just see that cigarette spot it keeps blowing the cigarette lighter fuse yeah another smoke coming out of there yep oh my god dude that's insane we almost caught this [ __ ] on fire just now what's going on down there oh i can smell it now you stick your head in here you can smell how hot it is here you can smell how hot it is so you can smell how hard it is you can smell how hot it is yeah you…
