TP2 is the GM RPO code for the oem dual battery setup. About half of wiring is in there, but there are still some connections to make between various engine/chassis/midbody harnesses and to the solenoid and all that other stuff.Is TP2 an efficiency or durability rating?
Was slightly disappointed on the amount of space in my second battery compartment was only able to fit a group 34 battery as i don’t plan on getting rid of the outter bracket bolt down area
After don’t know how many trips to the store mapping out the detailed schematic first is the way to go have $170 worth of 4 gauge wire that i need to find a home for due to lack of detailed planning
