I am a bit confused by a couple things:
The 1s does not include a high speed valve.
The 1s does not have a green wire that I am aware of.
What does the dealer say regarding wiring?
On the 1s, the relay should be wired to the plug for the pump. The red wire to + on the battery, the black wire to the - on the battery, the purple wire to a circuit that provides 12v+ when the ignition is in the on position.
The loose thin black wire from the plug goes to the boost pressure switch, the loose thin grey wire from the plug goes to the other terminal on the switch. The boost pressure switch is a normally closed relay that opens on the set boost pressure - it is not polarity sensitive to the black and grey wires. The boost pressure switch will control the pump on/off operation, properly wired it will not run all the time. As long as the grey wire is grounded the pump will not run, when the grey wire does not sense ground the pump will run.
If you have a 2c or 2d the wiring is more complicated.
