• Fit Power Support Wires (for Dual Bank board only)
Applies only to dual bank Type 4 board: S14 KA24DE (1996), A32 VQ30DE (1995-1996), Z32 300ZX (1996).
Not required for the normal Type 4 board as used on all other vehicles.
Due to the higher current draw of the dual bank board it is necessary to fit additional power and ground wires
from the ECU to the board for it to function correctly.
Run wires as follows
Adaptor Pin 1
> ECU W020 pin 1 (5V power)
Adaptor pin 40 > ECU W020 pin 40 (Ground)
