I am considering two different wiring plans. One copying the fleet/service wiring that I had on my Dodge truck. The drawback aside the addition of the heavier gauge wiring is how many brass shunts to add to the back of the amp guage due to access, obviously more is safer. The other option is a remote shunt (they come in different amp ratings) mounted in the engine compartment running two 14ga wires to the amp guage and one 6ga from the shunt to a insulated terminal post mounted on the passenger side of the bulkhead to replace the splice connection. The problem is the amp rating of the shunt needed to not fry the guage.
