EAS Pin out
The page numbers refer to the pages in the Air Suspension Circuit Operation section of the RAVE manual.

Pin	Page	Description
1	P3	Power. 12V via the 'delay' relay that keeps things turned on after the ignition is turned off.
2	P6	Left Rear height sensor power.
3	P6	Left Front height sensor power.
4	P6	Left Rear height sensor signal.
5	P6	Left Front height sensor signal.
6	P6	No connection inside and out.
7	P4	Data line to ride height panel switch. This and its partner pin 25 are 'open collector' outputs so they pull low but do not drive the line high. There are resistors at the switch to do this so the lines actually work on 0 to 5 volts.
8	P5	Switched 12V output to drive compressor relay.
9	P3	Exhaust Solenoid driver.
10	P3	Left Front Solenoid driver.
11	P3	Left Rear Solenoid driver.
12	P7	Some sort of speed signal.
13	P3	Pressure. Closed at >10bar, open at <8.5bar. Connects to Pin 1 power.
14	P8	Some sort of signal. Probably handbrake and gear.
15	P4	Dashboard Inhibit switch. GND when pressed and 12V via bulb when released.
16	P5	Compressor overheat. GND when normal, OC when overheated.
17	P2	Datalink to Testbook.
18	P5	Ground.
19		No connection in harness. Internally connected to pin 1.
20	P6	Right Rear height sensor power.
21	P6	Right Front height sensor power.
22	P6	Right Rear height sensor signal.
23	P6	Right Front height sensor signal.
24	P6	Height sensor common return.
25	P4	Clock line to panel switch.
26	P3	Inlet Solenoid driver.
27	P3	Right Front Solenoid driver.
28	P3	Right Rear Solenoid driver.
29		No connection in harness. Internally connected to pin 18.
30	P5	Some sort of engine speed signal.
31	P7	12V input when brakes are applied.
32	P4	UP switch. GND when pressed.
33	P4	DOWN switch. GND when pressed.
34	P2	Input. Probably special power up mode.
35	P2	Datalink to Testbook.

These are the connection points by name.
