Logan Learns How To Wire Relays! LSA Monte Carlo & Turbo Escalade Test Drive

What happens here

The task is to run a new, legitimate 12V constant power wire to the transmission's connector. The original faulty wire is part of a complex harness where finding the exact break would be too time-consuming. The helper pulls the existing wire assembly out from under the car, up through the engine bay, to access the connector. The plan is to create a new connection using non-insulated terminals and heat shrink for a more robust and lower-profile connection than the original solder heat shrink connectors.

Goal: Establish a reliable constant 12V power supply to the transmission.

Tools and materials

  • Crimping tool — Crimping terminals
  • Heat gun or mini torch — Shrinking tubing
  • Heat shrink tubing — Insulating and protecting connections
  • Non-insulated terminals — Making secure electrical connections
  • Wire — New 12V power line
  • Wire cutters — Cutting wires
  • Wire strippers — Stripping wire insulation

we're on the right track at least now we figured out that for whatever reason the transmission connector wire that gets 12 volts was not getting 12 volts constant from the battery instead of trying to find out where it's broken in there we're just going to run a new one we'll run it to a constant 12 volt spot either the battery or that little thingy on the firewall there is a hot spot um something like that so that will require uh cutting splicing and heat shrink can you handle it yes are you 100 sure yes well that's good because even if you weren't 100 sure you were gonna figure it out anyway because lesson of the day you don't need to be 100 sure how to do something before starting to do it just start doing it and figure it out and don't be afraid to mess it up okay you ready yes let's go i think remember that time that we did the lights and caught on fire yeah yeah that's uh check out the monte carlo playlist if you want to see all that stupid stuff we tried to put led lights in here and for some reason it didn't work and it caught on fire stuff so yeah good times not really uh yeah it's just temporary taped up in here but you're doing this not me so why don't you pull that out pull it out pull the connector out of the transmission look at this sock game one point here kachow do you have to turn it um counter clockwise okay now we gotta fish it out up for the top oh you can't pull it this way no no because it originates up there so we'll pull it up through there so what we're going to do is it joins up down there oh yeah we gotta unplug that o2 sensor we found out that this car will not start if the o2 sensor is not plugged in you pull it up through okay yeah that was just the test yeah that was the test wire oh i think you pulled it up through the wrong spot you need to pull it up this way now you know i need to fight my urge to just like jump in and start doing it to try to help you because i need to let you figure these things out well you put the freaking car up to your height not mine so thank you for that well i made it so it was easier to do stuff underneath it i can fit underneath it better than you that's true yeah she's unplugging the oil pressure sensor right now more room on there here's the thumbnail right here yeah okay it's like literally like through this giant thingy yeah so what we're gonna do is we gotta pull up as much as we can we're gonna take this wire and like actually connect this legitimately to here run it up through this…
