I really want to buy a BLUETTI Alternator Charger 1. I have a 2024 Toyota Corolla and it is still under warranty. I’m not afraid to get access through the firewall to the battery, I’m just having a problem finding a place to go through the firewall safely. It’s difficult to access the area that I can go through and I do not want to just poke around. If I had a factory service manual it would help, but it is very hard to find one and ever expensive.
Does anyone have any idea where to go through the firewall? Drivers side or passenger?
Welcome to the forum @chris84 !! Not sure about your specific vehicle to be honest but it might not hurt to stop by a local car audio place and pick their brains? They make those runs a lot and might be able to give you some more specific guidance and help you out? Plus it’s always nice to support the local guys/gals! Keep us posted when ya get it all dialed in!

Searching for information and never thought of a place that goes through firewalls with wiring for a living.
Thank you. I will let you know what I find out and if it goes like I hope I will be buying a new Bluetti Charge 1. Can’t wait to be charging my Bluetti faster in the car.
