I’ve been working on some upgrades for my GMC Sierra and I’m running into some issues with the wiring. Specifically, I need a detailed wiring harness diagram to make sure I’m connecting everything properly, especially since I’m planning to install a new sound system and possibly some custom lights.
Background
I have a 2018 GMC Sierra and I want to ensure that I’m making the right connections to avoid any electrical problems down the road. I’ve done some basic modifications before, but this is my first time diving into the wiring aspect.
What I’m Looking For
- Wiring Diagrams: If anyone has access to a detailed wiring diagram for the 2018 Sierra, that would be a huge help.
- Tips: Also, if you’ve had any experience with custom wiring in Sierra models, I’d love to hear about your experiences or any pitfalls to watch out for.
- Resources: Any links to good resources, diagrams, or tutorials would be appreciated.
Additional Info
If it helps, I’m focusing on the following components:
- New audio system (head unit and speakers)
- LED lights for the bed
- Maybe future upgrades like a dash cam
Thanks in advance for any assistance you can provide. I’m eager to get this project rolling but want to do it right. Let’s see if we can figure this out together!
