Overview

This guide shows you how to wire your S&B Particle Separator to the Switch-Pros SP9100 power management system, giving you direct control of the separator through your Switch-Pros switch panel.

Step 1: Cut the Harness Plug

Begin by removing the plug on the S&B harness that normally connects to the bus bar. Cut the harness at the location shown below:

Step 3: Wiring to the Switch-Pros Module

Wire each lead as follows:

  • Red (Power): Connect to the positive battery lead going into the Switch-Pros Power Module.
  • Black (Ground): Connect to a chassis ground, ideally the same one used by the SP9100 module.
  • Orange (Accessory): Connect to the output of any Switch 1–4 on the SP9100 panel.

⚠️ Important: Leave the relay and fuse inline on the S&B harness. These components are essential for proper circuit protection.
