Does anyone have a factory number for the positive wire for the parallel set up?

This is all that is needed plus batteries. The positive battery cable routes under the motor at the front of the oil pan near some other cables and includes clips to attach it to a plastic piece that already has holes in it for the cable clips. It then attaches to the starter on the same stud as the main battery.I attached the negative cable to the motor at a threaded hole in the head near the alternator. Exactly what i did plus bought 2 brand new diehard gold batteries..

I have this set up already. If I disconnect the primary battery on the passengers side and try to start the car, it won't start. I initially wanted the aux. battery to be a back up for starting the car.
You need the tp2 rpo option then @intheburbs has it written up on here somewhere or there are a few ways to approach the dual battery setup.
