INSTALLING THE 1041820 WIRING KIT (WHEN USING THE ORIGINAL 7W9609 HARNESS)
This portion of the instruction is to be used when
* Installing the 1041820 Wiring Kit when the original 9Y1606 Harness Assembly (Engine) has been replaced and still using the 7W9609 Harness Assembly (Junction Box)
Parts Removal
1 Locate the OPSI Identification Tag in the junction box
This is the oil pressure switch that has three connector openings, two that have wires
* The first wire is marked OPS1-1-ESS5
* The second wire is marked OPS1-3-TS4 and
* The third opening has a clear plastic plug inserted in the housing
2 The clear plug must be removed before installation of the 1041820 Wiring Kit
Use a 6V3008 Insertion Tool to
* Press the clear plug OUT of the housing from the INSIDE of the junction box outward
Complete the removal by
* Grasping the clear plug, from the BACKSIDE of the junction box, with needle nose pliers and pull it the remainder of the way out
