Default Tein EDFC control unit wiring question

So my friend and I installed the Tein EDFC Control unit today. There's a harness with 4 wires: red - accessory power, black - ground, yellow - constant power, green - illumination. We hooked everything up and thought everything was correct. Fire up the car and noticed the unit wouldn't turn on automatically. So we clicked the power button and the unit turned on. We had no problem using the unit to set the stiffness and use the pre-program feature to program settings. But once we turn off the power and turn the unit back on, the settings are gone. So basically 2 issues...

1. Unit does not turn on when ignition is on. I hate having to click an extra button every time I start up the car.

2. The pre-programmed settings are gone when the unit is restarted.

Thanks in advance!

Hey Alberto, does your unit power on when you turn the car on or you also have to click the power button?

The first time or if I disconnect the battery I have to turn it on. After that it stays on and stores the settings. I wanted my EDFC backlit all the time so I wired it like that, no illumination on it.

Hmm.. sounds like it's also the constant power wire then. The unit probably doesn't remember the last power setting was "on" when the car fires up. I'll look into that wire and see what we did wrong. Thanks!

Right. Sounds like it's definitely the yellow wire. Next Sunday it is!

The interior is like rainbow color now.. Red light from the AEM gauges, yellow light from the OEM lights, orange from the OEM gauges, now green from the tein EDFC controller... I just need some purple and blue and it'd be complete!

Hey Alberto, so your controller is basically on 24/7 even when the engine is shut down?
