(2)Mount the rack sensor main body to the pump main body.
(3)Fix the pump lever at full.
(4)At supply voltage V1, pump speed N1 and rack position Ra, confirm that the amp's output voltage is Vist.
(5)Move the pump lever two or three times.
(6)Set again to full.
(7)Confirm that the amplifier output voltage is Vist.
(8)Fix the caution plate to the upper part of the rack sensor.

2. Locate wire 405-GY on the main cab harness near the connector exiting the cab wall on the right hand side, as shown by arrow.Cut this wire close to the connector. Splice it and the wire just assembled using an 8S4626 Splice. Be sure to splice to the portion of the wire that goes into the cab harness.3. Connect the 7N9738 Housing to the two pin connector on the 8X9862 Harness Assembly (housing containing 405-GY). Clip with a 3T3048 Clip Assembly.Installation of Ether (Chassis) Wiring Harness
The ether chassis harness for MPPS is different than the one called out in the AEIS Special Instruction.* Substitute 8X8468 Harness Assembly for 8X7653 Harness Assembly on the 785 Trucks.* Substitute 8X8467 Harness Assembly for 8X7652 Harness Assembly on the 789 Trucks.Follow the installation procedure outlined in the AEIS Special Instruction for the Ether Chassis Harness Assembly. Be sure to use the 8X8466 Wire Assembly for the 785 Trucks or the 8X8429 Wire Assembly for the 789 Trucks. This is the new harness code plug required with MPPS.Installation of 8X8469 Ether (Engine) Wiring Harness
The 8X7106 Engine Harness on the AEIS is replaced with 8X8469 Harness Assembly.Follow the installation procedure outlined in the AEIS Special Instruction for the 8X7106 Harness Assembly. In addition, the following steps need to be performed. 1. Route the end of the harness with the 8T8732 Receptacle to the 3E3530 Electronic Control Group (oil pressure sensor) installed at the right rear of the engine as shown.2. Connect the three pin receptacle to the connector on the 3E3530 Electronic Control Group (2) and clip into the 9X3495 Clip Assembly (7) installed earlier. Use 3S2093 Straps (8) to loosely secure the harness to the top rear of the engine as shown.3. Remove the 8W3048 Harness Assembly that is connected to the remaining 6T7663 Oil Pressure Switch (9) and was connected to the 6T7663 Oil Pressure Switch (9) that was removed.4. Connect an 8X8337 Harness Assembly (10) to the one remaining oil pressure switch and reconnect to the engine harness. Clip with the existing clip. DO NOT tighten the straps or clips until all new wiring harnesses have been installed so any repositioning or adjustments can be made as necessary.Checking the Automatic Ether Injection System
* The system check-out will be same as for the AEIS with the following change: "A5" harness code on the 785 (indicates 3512 application) or "A6" harness code on the 789 (indicates 3516 application) for two seconds.Retrofit to an Existing AEIS System
