Big 3 upgrade on my Buick Enclave

[Tigress18]

I'm working on doing the Big 3 upgrade on my Enclave and I just added a high-output alternator and a lithium bank for the amps, now I'm figuring out the best way to run multiple runs of 0 gauge wire, has anyone done this on a Buick SUV before?

If you're running multiple 0 gauge wires in your Enclave, it's a good idea to run separate positive wires from the alternator to each battery if you've got more than one. Make sure to use good OFC wire, and put a fuse near the battery (around 300A should do). Keep the wires away from heat and moving parts. It's also smart to add extra ground connections from the engine to the chassis to improve grounding and reduce noise. Just make sure to secure everythin nice and tight with grommets and zip ties. Good luck with it

Cool setup, are you planning to run the wires all together in one harness, or separate them for different circuits?

Running separate positives and adding extra grounds makes sense, I'll definitely use OFC wire, fuses, and keep everything secure away from heat and moving parts

Yeah I'm thinking separate runs for each circuit to keep things organized and make troubleshooting easier down the road, trying to keep it clean and efficient
