Field AH-5 Height Controller for UZZ31

Although 3rd party height controllers such as the Field AH-5 are readily available for UZZ31 Soarers, they do not appear to be compatible with UZZ32 Soarers.

Wiring appears to consist of:

• 4 inputs
• 4 outputs
• power
• ground

Power and ground pins are spliced into the existing circuit. The others appear to be a case of diverting the 4 x sensor inputs into the controller and then sending the (modified) values into the Soarer's suspension controller.

• PIN B2 (Purple wire) - SHFR = Suspension Height Front Right ?
• PIN B3 (Pink wire) - SHRR = Suspension Height Rear Right ?
• PIN B10 (Green wire) - SHFL = Suspension Height Front Left?
• PIN B11 (Blue wire) - SHRL = Suspension Height Rear Left ?
• PIN A14 (Black wire) - assumed to be earth but does not seem to match with diagram
• PIN A8 (Red wire) - assumed to be ignition but does not seem to match with diagram

All other wires appear to be straight pass-through for connectors A and B, except for the handful of pins (A7, A18, A19, A21 and B4) that are not used. Connectors C and D are not used at all by this controller.
