Les.

"Identify the G.P.S. wire harness coming from the gearbox, ending with the light grey connectors under the seat on the left subframe rail, and disconnect the multi-plug.
Snip the 4th, 5th, and 6th gear wires. (Light Green/Yellow, Light Green/Black, and Light Green/White respectively.)
Identify the 3rd gear wire (Light Green/Green) and as with the previous wire splice, remove 8-10mm of insulation from it.
Do not cut the Light Green/Green wire, only remove its insulation.

Solder 4th, 5th, and 6th gear wires from the G.P.S. to the 3rd gear wire, use plenty of flux to ensure a perfect connection.

Insulate the soldered connection and the bare ends of the 4th, 5th, and 6th gear wires to the PGM-III to complete the splice"
