Bulkhead Instrument panel bypass.

JMO... the mopar charging system has NO perfect spot to pull power for accessories. With the bulkhead and ammeter in the mix, you have to choose alternator or battery side.

My way of deciding, if the item will run primarily when the engine is running, alternator side. When you have things like fans/stereos they can be on when the engine is off, where do you pull power.

Any instructions that have a comment that you want to attach power at battery, so you have "full battery power", the writer has no idea how an automotive electrical system works.

The Mad article is great for how things work, not a fan of the fix/approach.
