2. Connect the orange NOSbus wires to the master controller. See section 2.5.

2.3 Slave Controller Installation
1. If the optional slave controller is being used (PN 15978NOS), install it now. The slave controller offers an additional 2 stages of nitrous
capability. Fasten the unit in the same manner that that master controller is installed.
2. The slave unit wiring and colors are the same as the master controller. The slave unit does not have the USB cable connector,
manifold vacuum/pressure input, or fuel pressure sensor input. Wire it per section 2.1 above. See Figure 2 below.
3. Connect the orange NOSbus wires. See section 2.5.

2.4 Wide Band Oxygen Sensor Controller Installation
1. If the optional wide band oxygen sensor controller is being used (PN 15979NOS, requires sensor sold separately, PN 534-194 for NTK
sensor or PN 534-198 for Bosch LSU4, NTK recommended for leaded fuels) mount it now. The controller has a brown wire loop on it.
If the Bosch sensor is being used, this wire MUST be cut. Cut the wire and place heat shrink over both cut ends. If the NTK sensor is
being used, do not cut the wire.
