I was skeptical about tackling this myself, but seeing these tips makes it seem more doable. Thanks for the motivation, everyone!
I understand your frustration! A common issue with trailer brake wiring is faulty connections. Always check for corrosion or loose wires at the 7-pin connector. A multimeter can help you troubleshoot effectively.
Absolutely! I had a similar problem last summer. I ended up replacing the wiring harness entirely. Sometimes, it’s just easier than trying to repair.
Don’t overlook the ground wire! I’ve seen many people assume everything else is fine, only to find out their ground connection was the culprit. Make sure it’s tightly secured and clean.

Good point! It’s easy to miss! Ground issues can cause so many unexpected problems. Anyone have tips for testing the ground wire?
In terms of testing, using a continuity tester works great! You can also check with the vehicle running to see if the voltage is set correctly at the plug.
If you’re really stuck, I’d recommend a YouTube video tutorial. There are some excellent step-by-step guides out there for Chevy wiring. Just be careful to choose a reputable source.
True! I learned quite a bit from one of those! But make sure to check the comments sections for updates—sometimes the video can miss crucial details.

I’m just curious, how do others feel about color coding? I find it confusing sometimes, especially when wiring is weathered and faded. Wouldn’t it be helpful to have a standardized color code?
A standardized color code would definitely make things easier! However, I think it could lead to contention if manufacturers start changing schemes. It’s a slippery slope!
