- Connect wire harness (5) to the existing chassis harness.
Note: The chassis harness may be bundle tied with a strap. Cut the strap in order to make the terminal connection.
- Locate the electrical wire connected to the high-pressure switch below the floor of the cab.
- Fasten the high-pressure switch wire to terminal "K849 YL" and "235 BK" of the platform harness.
Note: The platform wire may be secured in the harness. Separate the wire from the bundle in order to make the terminal connection.
- Fasten the high-pressure switch wire to the bottom of the cab floor using clip (3), washer (8), and bolt (7) .
- Secure the excess high-pressure switch wire to the high-pressure switch using strap (1) .
- Secure the excess platform harness in place using strap (1) .
- Secure wire harness (5) inside the cab and below the cab floor as needed. Use straps (1) and straps (2) .
